Introduced a dmi rest demo csit stub

- Introduced a new response code 0 for data operational success response.
- Created a new dmi plugin rest stub for demo and performance testing.
- Removed dmi plugin stub of wiremocked.
- Updated parent pom to add newely created demo stub.
- updated docker compose to add neww demo stub with profile for CSIT,
