Align the hazelcast cluster names

- We need to align the hazelcast cluster names as members of the same
  cluster can join each other. We will still have exclusivity as the
  instance names and configs are different for each distributed object.
- Exposing env variable to override the cluster name depending on the
  env it is run on.
- Modified test cases to validate the cluster names as well
