[issue33897] Add a restart option to logging.basicConfig()

[Raymond Hettinger]

New submission from Raymond Hettinger <raymond.hettinger at gmail.com>:

Once a logger or basicConfig() has been called, later calls to basicConfig() are silent ignored.  The makes it very difficult to experiment with or teach the various options at the interactive prompt or in a Jupyter notebook.

What we have:

    >>> import logging
    >>> logging.warning('Too much data')
    WARNING:root:Too much data
    >>> logging.info('Volume is at 80%')
    >>> logging.basicConfig(level=logging.INFO)
    >>> logging.info('Volume is at 80%')
    >>> # Note, no output was created

What we need:

    >>> import logging
    >>> logging.warning('Too much data')
    WARNING:root:Too much data
    >>> logging.info('Volume is at 80%')
    >>> logging.basicConfig(level=logging.INFO, restart=True)
    >>> logging.info('Volume is at 80%')
    INFO:rootVolume is at 80%
