feat(translator): vrf support in backend

[crankynetman]

This is a bit of large MR, sorry. This MR does a few things, all of it under the guise of supporting VRFs with GoBGP:

1. Allows you to perform all of the translator actions inside of a VRF or on the base routing instance.
2. Split out websocket message parsing a bit and added a lot more validation. This also means that the process() function is a lot more straight-forward and that logic was broken apart.
3. We now use redis 🎉 ! This is because GoBGP can't give you just a single prefix's announcement status so we had to write that ourselves.
4. A ton of loggers added all over the place as well as docstrings.

closes #44, implements the translator part of #35

I can live with the slight drop in coverage if you believe it's not a problem
