Python LSP selection

[lars-petter-hauge]

Keeping an issue here for documentation.

Pyright:

• Base of pylance used in vscode (microsoft develops both)
• Maintainers have chosen to keep the server low on features, rather focusing on pylance for feature richness (https://github.com/microsoft/pyright/issues/4325) - which of course is a bummer as it is closed source and exists in vscode.
• Fairly fast and contains most of the sought after features.

Pylyzer:

• Very fast lsp built with Rust.
• One major draw back currently, does not support virtualenv https://github.com/mtshiba/pylyzer/issues/22

Python-lsp-server

Jedi-language-server:

• Simple to install and relies on the jedi tool
• Jedi tool mainly focus on autocompletion, goto definitions
• lacking diagnostic checks

FYI, basedpyright is another language server intending to address this gap.
