Improved CLI

[mpangrazzi]

The following provides:

• We use now fastapi[standard] as a dep, so we also have FastAPI CLI and Typer.
• CLI commands refactoring and rewrite using Typer instead of click (for nicer UX and easier to add CLI tests).
• Exposed uvicorn's --reload and --workers to hayhooks run commands.

Now there are base CLI commands:

$ hayhooks run
$ hayhooks status

and pipeline CLI commands:

$ hayhooks pipeline deploy
$ hayhooks pipeline deploy-files 
$ hayhooks pipeline undeploy

Sample UX:

hayhooks-cli.mp4

This looks nice.
(I don't know Typer, so initially I struggled a bit to understand context and callbacks.)

Some questions:

• this partially breaks the existing CLI, no?
• (As other recent features and improvement, this would need comprehensive docs.) README needs to be updated as well. When will we do this? When we release a new version?

@anakin87 thanks for reviewing!

this partially breaks the existing CLI, no?

Yes. Actually, I've simply moved pipeline-related ones under pipeline subcommand.

(As other recent features and improvement, this would need comprehensive docs.) README needs to be updated as well. When will we do this? When we release a new version?

Absolutely! I am updating docs now (also README of course), then I was thinking to do a release. WDYT?
