Loop assign GWs to different VS

Overview

RD has a scenario like the fallowing:

• 3-node cluster, each node with GW services enabled, all under Default VS by default

• Create VS-1 and assign GW1 to VS-1

• Create VS-2 and assign GW2 and GW3 to VS-2

• Create VS-3, assign GW1 to VS-3, and delete VS-1

• Create VS-4, assign GW2 and GW3 to VS-4, and delete VS-2

• So on and so forth, after each round of allocation, you need to check the health status of ctdb under the current VS

Considering that manual testing can be time consuming, write a test script and run it overnight or more rounds (e.g: loop 1000 times) and see how the test works the next day.
