Enhance it for cluster-restart tests

[jt2594838]

The current IT framework often fails on tests that involve cluster restarts, due to port occupation. It is because some nodes may create clients that occupy vital ports of the nodes that are restarting. To avoid this, the port detection utility is refactored to list the PIDs that are occupying the ports. If the PID is associated with a database node, the node will also be restarted to release the port.

By the way, when DataNode or ConfigNode exits with an exception, it will try to return a more precise code other than -1.
