Move Jedi to use LSP instead of internal registration

[rchiodo]

This is the second step in making a working intellisense engine for notebooks. Could be based on this:
https://github.com/pappasam/jedi-language-server

@rchiodo What can I do to validate this?

[rchiodo]

Set your language server to Jedi and then set this experiment to on:

    "python.experiments.optInto": [
        "jediLSP",
    ],

Reload VS code and then attempt intellisense in a normal python file.

[IanMatthewHuff]

Doesn't seem to be working for me. I get this message and no intellisense:

[rchiodo]

Are you doing this with the vsix bits or with your debug bits? You need to install the server manually if you're using debug bits

[IanMatthewHuff]

I was using debug bits. I'll just swap over to a VSIX seems easier than installing a server manually.

[rchiodo]

You run this to install the server (as well as other requirements)

python -m pip --disable-pip-version-check install -t ./pythonFiles/lib/python --no-cache-dir --implementation py --no-deps --upgrade --no-user -r ./requirements.txt

[IanMatthewHuff]

Not if I use the VSIX though, right? With the most recent insiders VSIX I get the same result.

[rchiodo]

Yeah it should work with the VSIX. Maybe something has since broke. There's no tests making sure this continues to work

[rchiodo]

This would be on the python team to 'fix' if it doesn't work. Or at least the work would happen in the python extension.
