Filter on private properties of CM Handles

- Moved cm handle query validation to cps-ncmp-service (where it belongs!)
- Added new enum type for private/public field types
- Created new methods for private and public queries
- Added new REST endpoint
- Created service methods for filtering on different types of properties
- Refactored getPublicPropertyPairs and queryCmHandleAnyProperties
- Added unit test for the controller layer
- Fixed refactoring suggestions
- Imporved code coverage with unit tests
- Refactoring
- Added new functionality to NcmpRestInputMapper
- Updated version number to 3.2.1-SNAPSHOT and updated release-notes.rst
