cb14cdd774 raftexample: Fix recovery from snapshot 
* If there is a snapshot, HTTP server won't start.
* Resotring form snapshot occurs after replaying WAL.
* When taking a snapshot, the last change is not applied to the state machine yet.

f89b06dc6d raft: provide protection against unbounded Raft log growth 
The suggested pattern for Raft proposals is that they be retried
periodically until they succeed. This turns out to be an issue
when a leader cannot commit entries because the leader will continue
to append re-proposed entries to its log without committing anything.
This can result in the uncommitted tail of a leader's log growing
without bound until it is able to commit entries.

This change add a safeguard to protect against this case where a
leader's log can grow without bound during loss of quorum scenarios.
It does so by introducing a new, optional ``MaxUncommittedEntriesSize
configuration. This config limits the max aggregate size of uncommitted
entries that may be appended to a leader's log. Once this limit
is exceeded, proposals will begin to return ErrProposalDropped
errors.

See cockroachdb/cockroach#27772

Save the snapshot index to the WAL before saving the snapshot to the
filesystem. This ensures that we'll only ever call wal.Open with a
snapshot that was previously saved to the WAL.

0cb304ec61 contrib/raftexample: fix restart path 
The ConfChange fix crashes WAL replay because it assumed the node
always exists. Additionally, restart on a single node cluster
would deadlock because it had the wrong raft HardState.

To fix, replay path now goes through the regular raft loop.

Fixes #4474
