bf3e7033e9 etcdserver: Move Read/Update methods on Meta bucket to one place 
There are still some left like compact keys, but they will require more
work to avoid circular dependency.

66752fef2f Represent bucket as object instead of []byte name. 
Thanks to this change:
  - all the maps bucket -> buffer are indexed by int's instead of
string. No need to do: byte[] -> string -> hash conversion on each
access.
  - buckets are strongly typed in backend/mvcc API.

ab586cd463 Persists Term in the (bbolt) Backend. 
Additional layer of protection, that allows to validate whether we
start replaying log not only from the proper 'index', but also of the
right 'term'.

865df75714 Save raftpb.ConfState in the backend. 
This makes (bbolt) backend a full feature snapshot in term of WAL/raft,
i.e. carries:
  - commit : (applied_index)
  - confState

Benefits:
  - Backend will be a sufficient point in time definition sufficient to
start replaying WAL. We have applied_index & confState in consistent
state.
  - In case of emergency a backend state can be used for recovery

b1c04ce043 Applying consistency fix: ClusterVersionSet (and co) might get no applied on v2store 
ClusterVersionSet, ClusterMemberAttrSet, DowngradeInfoSet functions are
writing both to V2store and backend. Prior this CL there were
in a branch not executed if shouldApplyV3 was false,
e.g. during restore when Backend is up-to-date (has high
consistency-index) while v2store requires replay from WAL log.

The most serious consequence of this bug was that v2store after restore
could have different index (revision) than the same exact store before restore,
so potentially different content between replicas.

Also this change is supressing double-applying of Membership
(ClusterConfig) changes on Backend (store v3) - that lackilly are not
part of MVCC/KeyValue store, so they didn't caused Revisions to be
bumped.
