Test Steps:
1 check the current peer status
2 detach one of the valid nodes which is already part of cluster
3 stop glusterd on that node
4 try to attach above node to cluster, which must fail with
Transport End point error
5 Recheck the test using hostname, expected to see same result
6 start glusterd on that node
7 halt/reboot the node
8 try to peer probe the halted node, which must fail again.
9 The only error accepted is
"peer probe: failed: Probe returned with Transport endpoint is not
connected"
10 Check peer status and make sure no other nodes in peer reject state
