Improve documentation, remove dead code plus some minor refactorings
This improves our code-to-comments ratio by a lot.
On the refactorings:
- Simplify the cluster join mode to just a single protobuf message -
a node can either join an existing cluster or bootstrap a new one.
All of the node-level setup like hostname and trust backend is done
using the setup call, since those are identical for both cases.
- We don't need a node name separate from the hostname. Ideally, we would
get rid of IP addresses for etcd as well.
- Google API design guidelines suggest the `List` term (vs. `Get`).
- Add username to comments for consistency. I think the names provide
useful context, but git blame is a thing. What do you think?
- Fixed or silenced some ignored error checks in preparation of using
an errcheck linter. Especially during early boot, many errors are
obviously not recoverable, but logging them can provide useful debugging info.
- Split up the common package into smaller subpackages.
- Remove the audit package (this will be a separate service that probably
uses it own database, rather than etcd).
- Move storage constants to storage package.
- Remove the unused KV type.
I also added a bunch of TODO comments with discussion points.
Added both of you as blocking reviewers - please comment if I
misunderstood any of your code.
Test Plan: Everything compiles and scripts:launch works (for whatever that's worth).
