Add share link feature

[fcollonval]

The need of installing another extension to generate a shared link fade away now that you need to explicitly install this extension to enable live collaboration.

This add the share link feature through a button next to the user menu bar (top right).

It also simplifies the code by dropping the backend code (compared to jupyterlab-share-link) as there is no reason to provide link to another server than the current one.

It also simplifies the code by dropping the backend code (compared to jupyterlab-share-link) as there is no reason to provide link to another server than the current one (a second jupyter server via jupyter-server-proxy).

To give more context about this, the original motivate in jupyterlab-link-share was to provide the correct token when running on Binder.

Would be happy to archive https://github.com/jupyterlab-contrib/jupyterlab-link-share if it is not necessary anymore.

Thanks @jtpio for highlighting that peculiar point.
It would be great if indeed this could work on Binder - haven't tested yet.

Another point I'm missing is the support for notebook V7. But I guess this could be tackled in a specific issue as there is also a question about what to do with the side panel.

For Notebook 7 support, we could use the appName or something similar to detect the distribution and reposition the different widgets. It would be great to standardize it (or maybe a different approach) so every extension can rely on that to detect the distribution.

Thanks!
