• Create a command which sends an RPC to Foyle to generate cells
• Resulting cells are inserted into the notebook
• A configuration option lets user set the address of the Foyle server

Related to stateful/runme#574

@sourishkrout Would you PTAL? The code is a bit rough (lots of lint errors); however I had some questions about how various things should be done and I thought you might be able to provide some pointers?

FWIW the code does work; I was able to run it and get suggestions provided by Foyle

@sourishkrout Sorry about that. I think its fixed.

One of the unit tests failed which is an easy fix. registerCommand is called an additional time for the Foyle/AI cmd.

@jlewi the fix is to increment it to 40.

Thank you @sourishkrout ; I fixed the test.

Merging. - The e2e integration test's failing because GitHub Actions are being finicky and have been under the weather with outages the last few days. It's not broken.
