use one hazelcast instance per jvm

- updated all the cache(distributed datastructures) to use the same instance config now.
- there will be just one instance per JVM now
- Better cleanup of hz instance in the testware
- Refactored the testware to verify the configs
- Expected Impact on lowering the memory usage, less number of TCP
  communications between members
- NOTE: we need to do a full regression as the changes impacts all the
  use cases which involves cache
