  -----------
  ovsdb-server: Replace in-memory DB contents at raft install_snapshot.

Every time a follower has to install a snapshot received from the
leader, it should also replace the data in memory. Right now this only
happens when snapshots are installed that also change the schema.

This can lead to inconsistent DB data on follower nodes and the snapshot
may fail to get applied.

Fixes: bda1f6b60588 ("ovsdb-server: Don't disconnect clients after raft install_snapshot.")
