Add withTrustLevel condition to CmHandle Query API

- Change untrustworthyCmHandleSet with trustLevelPerCmHandleMap
- Change trust level cache config accordingly
- Change device heartbet consumer accordingly
- Add json schema for device trust level
- Add with_trust_level enum into cm handle query conditions
- Add query cm handle by trustlevel function to cm handle
  queries
- Add query cm handle by trustlevel service to network cm proxy cm
  handle service
- Add unit tests and fix code smells
