Unify server release group

[znewton]

Description

It is painful to share code across R11s, Gitrest, and Historian due to the package and release group structure. This leads to a lot of code duplication and hacky workarounds, as well as a slower development cycle.

Breaking Changes

1. server/gitrest is GONE
2. server/historian is GONE
3. Gitrest and Historian Docker images are built within Routerlicious Docker image

Reviewer Guidance

I'm sure that I missed some aspects of this move that are important. Questions I know I was fuzzy on are:

1. Do we still need server-gitrest and server-historian pipelines?
2. Can we rename server/routerlicious to something better now that it includes routerlicious, tinylicious, historian, and gitrest?
3. Should the historian and gitrest kubernetes charts move to server/routerlicious/kubernetes?
4. Will this mean that gitrest, gitrest-base, historian, and historian-base will be published publicly in NPM with the same versions as R11s packages? Is that a problem or OK?

Zach and I discussed this briefly offline so I'll share the reservations I have here as well.

The major problem I see with this is that we have to ship (== release to npm) all packages in the release group when we release. Thus, everything that's not private gets published to npm. We already publish a bunch of "junk packages" that customers don't use or need, or "junk versions" that contain 0 changes except a version bump. I'd prefer to keep separate stuff that doesn't need to publish publicly/frequently.

We may eventually support releasing/version bumping only a portion of a pnpm workspace but today we don't.
