22925a1d2f raft: Remove redundant raft.Commit field. 
Keeping this field in sync with `raft.raftLog.committed` was
error-prone, so instead we synthesize the `HardState` on demand.

Fixes #4278.

896719c877 raft: use configured logger in raft/node.go 
Those three log statements in node.go have not been using the logger that was passed via `raft.Config`, but instead the default raft logger. This changes it to use the proper logger.

46bb2582fe raft: Call maybeCommit after removing a node. 
removeNode reduces the required quorum size, so some pending entries may
be able to commit after it is applied.

fbeb58d265 raft: no-op instead of panic for Campaigning while leader 
We need to be able to force an election (on one node) after creating a
new group (cockroachdb/cockroach#1384), but it is difficult to ensure
that our call to Campaign does not race with an election that may be
started by raft itself. A redundant call to Campaign should be a no-op
instead of a panic. (But the panic in becomeCandidate remains, because
we don't want to update the term or change the committed index in this
case)

1716d5858f raft/documentation: clarify progress's subjects. 
If I understand correctly, `progress` represents the states of follower. For
me, some comments weren't clear because it was missing the subjects of
`progress`. This adds more clarification on who is doing what. Please let me
know if I misunderstood anything. Thanks,

4c82b481a5 raft: improve behavior when snapshot fails 
etcd is going to support incremental snapshot, and we design to let it
send at most one snapshot out at first stage. So when one snapshot is in
flight, snapshot request will return error.

When failing to get snapshot when sending MsgSnap, raft prints out
related log and abort sending this message.
