LS Requests for dependents of Python extension.

This is a spike to answer the question if. Do we need to handle requests/notifications from dependents of Python extension.

There is no getting around exposing the languageClient to Jupyter. Based on investigations done here and for #19129 .

So, we will need to expose an API that provides the client. The client object provided by python extension will have to keep in sync with actual language client. Since process (LS server process and actual LS client object) lifetime management may have to be done by LS provider extensions ( Pylance), there are few things, such as client.start(), client.stop() have to be wrapped by the client object provided by the python extension.

A thing to note about server and client creation. An issue with the current model is that initialization options for servers are not provided by jupyter. See trustedWorkspaceSupport for Pylance or disableSnippets for Jedi.
