Bug 3570: Use SnapShot lastAppliedIndex for install snapshot

Follow-up patch for https://git.opendaylight.org/gerrit/#/c/21904/ to
use the captured Snapshot's lastAppliedIndex for the lastIncludedIndex
field in the InstallSnapshot message and the follower's matchIndex/nextIndex
once the install completes. This is in lieu of using the leader's snapshotIndex
which typically lags behind the lastAppliedIndex by 1 due to the trimming of
the in-memory log. This avoids the leader sending its last log entry
redundantly after the install completes as the last entry was included
in the snapshot.
