Introduce TVC CLI

[emostov]

Introduce the TVC CLI, with an eye bootstrapping scaffolding that will make it easy to extend with other commands.

• I included global args for base url and organization id. They are not used yet but I anticipate they soon will be once we hook up to the api
• There are still some rough edges like the approval by default getting printed to stdout. This is just a starting point
• In a few places I added env var parsing. The CLI args will take precedent over env vars, but I think the env vars are nice for things that won't change often or are hard to type, such as organization id, operator id, and api base. I also included deployment id since I figure that will be hard to type. I excluded env vars for args I anticipate to only be relevant for local development
• I started out with a "Pair" abstraction. This is premature, but will make it easy to implement operator keys with yubikeys, api, or other local formats like password encrypted file
• CLI e2e tests: tried to keep them high value without being too finicky whenever we make a change

I needed to bump this for compatibility with qos. I need to double check if this will break any pre-existing crates MSRV, but I hope not since they don't use qos

Not used, but figured I would include to show we can use these in the future

purposely included funky spacing and new lines to test the strip whitespace functionality
