Moxi port conflict when starting multiple server on the same node using cluster_run

Using ./cluster_run -n4 to start up 4 servers locally, and try testrunner to test XDCR with rebalance and failover.

Sometime moxi server is unable to start due to some port issue and ns_port_server just kept crashing. Looks it is not related to XDCR and is a generic issue.
