Create Base and Sample Performance Integration Tests

- added data (folders) for different models and json data
- added base and data for cps-ncmp (registry) specific test cases
- integrated Ahila's (large) openroadm model and data
  (corrected version provided by Lee Anjella)
- created profiles to exclude/include *PerfTest
- fixed dependency test check
- included integration test for overall coverage
- increased margings in existing perf test to reduce nordix intermitten failures
