Subject: Distributed map setup for Module and Data Sync

- Introduce the hazelcast dependency and check how the builds react to
  it.
- Data Sync and Module Sync Map config.
- Added basic test scenarios.
- Updating the artifact-id from hazelcast-all to hazelcast-spring and
  version is 4.2.5. (5.1.2 is latest but has known vulnerabilities)
- Refactored the code as per the onsite review session
- Upcoming : Actual sub-task which will use the distributed maps in
  respective use cases.

Issue-ID: CPS-1050
Change-Id: I60314c4ff95c267b186b20862aef93a5c389a971
