Nbconvert exporter entrypoint

[mpacer]

You can expose this package directly to nbconvert (so you could use jupyter nbconvert --to confluence your.ipynb) using entrypoints:

For example (from the docs):

setup(
    ...
    entry_points = {
        'nbconvert.exporters': [
            'simple = mymodule:SimpleExporter',
            'detail = mymodule:DetailExporter',
        ],
    }
)

With the current implementation, the minimum required parameters on the command line for the exporter entrypoint command line would be the following:

nbconvert --to confluence --ConfluenceExporter.url=<url of the page to update> \
  --ConfluenceExporter.username=<username> --ConfluenceExporter.password=<password> \
  mynotebook.ipynb

Specifying a password on the command line is not great for securty, so we'd probably need to move the code that reads it from an env var or the .nbconflux file to the exporter. That would make the minimum command line:

nbconvert --to confluence --ConfluenceExporter.url=<url of the page to update> mynotebook.ipynb
