Click CLI interface

[sneakers-the-rat]

Following https://github.com/sneakers-the-rat/journal-rss/pull/1/

Lets make a click CLI interface for launching the server. We'll also need it later for doing migrations and etc.

I think it would be great if we could use FastAPI to make an "admin" endpoint, and then we can use the .env file to store a token so we can have the CLI interface both start/stop the server and also communicate with it while it's running to be able to eg. Manually trigger a feed update.

Lets say root command is journal-rss, lets start with

• [ ] implement base click cli
• [ ] start - with option to fork the process into the background
• [ ] stop - obvi if we fork we need to stop
• [ ] serve - does the wsgi uvicorn thing have a dev and prod mode? This one would be prod mode that doesnt live refresh on code changes

And address future commands as needed.

Randomly, since you mentioned an admin endpoint - could this be useful? https://github.com/fastapi-admin/fastapi-admin
