This test performs following operations:<br>

1. Create multiple Partition Regions in 4 VMs<br>

2. Performs put()operations on all the partitioned region from all the VM's<br>

3. Performs destroy(key)operations for some of the keys of all the partitioned region from all
the VM's<br>

4. Checks containsKey and ContainsValueForKey APIs
