The xsite replication TCP connection does not get reestablished after the cache started.

To reproduce the issue:
0) block the tcp port between the 2 sites (such as 7800) which is configured for xsite replication
1) start both clusters
2) the 2 clusters are all up (no errors), but the xsite tcp connection is not established (e.g., by checking the netstat output)
4) now unblock the tcp port
5) check the xsite connection. It is not established. Hence, the xsite replication will still not work.
The expected behaviour would be, at minimal, it should show the xsite replication in error state. The better one is to ispn will try to re-establish the connection.
