Update nbgrader notebook metadata

Options
=======
The options below are convenience aliases to configurable class-options,
as listed in the "Equivalent to" description-line of the aliases.
To see all configurable class-options for some <cmd>, use:
    <cmd> --help-all

--log-level=<Enum>
    Set the log level by value or name.
    Choices: any of [0, 10, 20, 30, 40, 50, 'DEBUG', 'INFO', 'WARN', 'ERROR', 'CRITICAL']
    Default: 30
    Equivalent to: [--Application.log_level]

Class options
=============
The command-line option below sets the respective configurable class-parameter:
    --Class.parameter=value
This line is evaluated in Python, so simple expressions are allowed.
For instance, to set `C.a=[0,1,2]`, you may type this:
    --C.a='range(3)'

Application(SingletonConfigurable) options
------------------------------------------
--Application.log_datefmt=<Unicode>
    The date format used by logging formatters for %(asctime)s
    Default: '%Y-%m-%d %H:%M:%S'
--Application.log_format=<Unicode>
    The Logging format template
    Default: '[%(name)s]%(highlevel)s %(message)s'
--Application.log_level=<Enum>
    Set the log level by value or name.
    Choices: any of [0, 10, 20, 30, 40, 50, 'DEBUG', 'INFO', 'WARN', 'ERROR', 'CRITICAL']
    Default: 30
--Application.logging_config=<key-1>=<value-1>...
    Configure additional log handlers.
    The default stderr logs handler is configured by the log_level, log_datefmt
    and log_format settings.
    This configuration can be used to configure additional handlers (e.g. to
    output the log to a file) or for finer control over the default handlers.
    If provided this should be a logging configuration dictionary, for more
    information see:
    https://docs.python.org/3/library/logging.config.html#logging-config-
    dictschema
    This dictionary is merged with the base logging configuration which defines
    the following:
    * A logging formatter intended for interactive use called
      ``console``.
    * A logging handler that writes to stderr called
      ``console`` which uses the formatter ``console``.
    * A logger with the name of this application set to ``DEBUG``
      level.
    This example adds a new handler that writes to a file:
    .. code-block:: python
       c.Application.logging_config = {
           "handlers": {
               "file": {

                   # handler here then it will be disabled
                   "handlers": ["console", "file"],
               },
           },

CourseDirectory(LoggingConfigurable) options
--------------------------------------------
--CourseDirectory.assignment_id=<Unicode>
    The assignment name. This MUST be specified, either by setting the config
    option, passing an argument on the command line, or using the --assignment
    option on the command line.
    Default: ''
--CourseDirectory.autograded_directory=<Unicode>
    The name of the directory that contains assignment submissions after they
    have been autograded. This corresponds to the `nbgrader_step` variable in
    the `directory_structure` config option.
    Default: 'autograded'

    A key that is unique per instructor and course. This can be specified,
    either by setting the config option, or using the --course option on the
    command line.
    Default: ''
--CourseDirectory.db_url=<Unicode>
    URL to the database. Defaults to sqlite:///<root>/gradebook.db, where <root>
    is another configurable variable.
    Default: ''
--CourseDirectory.directory_structure=<Unicode>
    Format string for the directory structure that nbgrader works over during
    the grading process. This MUST contain named keys for 'nbgrader_step',
    'student_id', and 'assignment_id'. It SHOULD NOT contain a key for
    'notebook_id', as this will be automatically joined with the rest of the
    path.
    Default: '{nbgrader_step}/{student_id}/{assignment_id}'
--CourseDirectory.feedback_directory=<Unicode>
    The name of the directory that contains assignment feedback after grading
    has been completed. This corresponds to the `nbgrader_step` variable in the
    `directory_structure` config option.
    Default: 'feedback'
--CourseDirectory.groupshared=<Bool>
    Make all instructor files group writeable (g+ws, default g+r only) and
    exchange directories group readable/writeable (g+rws, default g=nothing only
    ) by default.  This should only be used if you carefully set the primary
    groups of your notebook servers and fully understand the unix permission
    model.  This changes the default permissions from 444 (unwriteable) to 664
    (writeable), so that other instructors are able to delete/overwrite files.
    Default: False
--CourseDirectory.ignore=<list-item-1>...
    List of file names or file globs. Upon copying directories recursively,
    matching files and directories will be ignored with a debug message.
    Default: ['.ipynb_checkpoints', '*.pyc', '__pycache__', 'feedback']
--CourseDirectory.include=<list-item-1>...
    List of file names or file globs. Upon copying directories recursively, non
    matching files will be ignored with a debug message.
    Default: ['*']
--CourseDirectory.max_dir_size=<Int>
    Maximum size of directories (in kilobytes; default: 100Mb). Upon copying
    directories recursively, larger files will be ignored with a warning.
    Default: 100000
--CourseDirectory.max_file_size=<Int>
    Maximum size of files (in kilobytes; default: 100Mb). Upon copying
    directories recursively, larger files will be ignored with a warning.
    Default: 100000
--CourseDirectory.notebook_id=<Unicode>
    File glob to match notebook names, excluding the '.ipynb' extension. This
    can be changed to filter by notebook.
    Default: '*'
--CourseDirectory.release_directory=<Unicode>
    The name of the directory that contains the version of the assignment that
    will be released to students. This corresponds to the `nbgrader_step`
    variable in the `directory_structure` config option.
    Default: 'release'
--CourseDirectory.root=<Unicode>
    The root directory for the course files (that includes the `source`,
    `release`, `submitted`, `autograded`, etc. directories). Defaults to the
    current working directory.
    Default: ''
--CourseDirectory.solution_directory=<Unicode>
    The name of the directory that contains the assignment solution after
    grading has been completed. This corresponds to the `nbgrader_step` variable
    in the `directory_structure` config option.
    Default: 'solution'
--CourseDirectory.source_directory=<Unicode>
    The name of the directory that contains the master/instructor version of
    assignments. This corresponds to the `nbgrader_step` variable in the
    `directory_structure` config option.
    Default: 'source'
--CourseDirectory.source_with_tests_directory=<Unicode>
    The name of the directory that contains notebooks with both solutions and
    instantiated test code (i.e., all AUTOTEST directives are removed and
    replaced by actual test code). This corresponds to the `nbgrader_step`
    variable in the `directory_structure` config option.
    Default: 'source_with_tests'
--CourseDirectory.student_id=<Unicode>
    File glob to match student IDs. This can be changed to filter by student.
    Note: this is always changed to '.' when running `nbgrader assign`, as the
    assign step doesn't have any student ID associated with it. With `nbgrader
    submit`, this instead forces the use of an alternative student ID for the
    submission. See `nbgrader submit --help`.
    If the ID is purely numeric and you are passing it as a flag on the command
    line, you will need to escape the quotes in order to have it detected as a
    string, for example `--student=""12345""`. See:
        https://github.com/jupyter/nbgrader/issues/743
    for more details.
    Default: '*'
--CourseDirectory.student_id_exclude=<Unicode>
    Comma-separated list of student IDs to exclude.  Counterpart of student_id.
    This is useful when running commands on all students, but certain students
    cause errors or otherwise must be left out.  Works at least for autograde,
    generate_feedback, and release_feedback.
    Default: ''
--CourseDirectory.submitted_directory=<Unicode>
    The name of the directory that contains assignments that have been submitted
    by students for grading. This corresponds to the `nbgrader_step` variable in
    the `directory_structure` config option.
    Default: 'submitted'

Examples
--------

    nbgrader stores metadata in the JSON source of the notebooks. Previously,
            we did not do a good job of validating whether this metadata was
            correctly formatted or not. Starting in version 0.4.0 of nbgrader, we
            are explicitly validating this metadata. This will require that you
            update the metadata in your old nbgrader notebooks to be consistent
            with what nbgrader expects.

            The `nbgrader update` command performs this metadata update for you
            easily. All you need to do is point it at a directory, and it will
            find all notebooks in that directory and update them to have the
            correct metadata:

                # update notebooks rooted in the current directory
                nbgrader update .

                # update notebooks rooted in the `class_files` directory
                nbgrader update class_files/

            Alternately, you can open all your notebooks with the "Create Assignment"
            toolbar and re-save them from the notebook interface. But, it will be
            more efficient to run the `nbgrader update` command to get them all in
            one fell swoop.
