ovsdb: Fix OVSDB disconnect replication bug

Browse Source 
Currently disconnecting from the replicator server means closing the
jsonrpc connection and destroying the monitored table names and
blacklisted table names.

This patch makes a distinction between disconnecting from the
remote server, applicable when the replication incurs in an error,
and destroying the remote server info, applicable when ovsdb-server
exits gracefully.
