Merge 2 'query' end points in NCMP

- merge two endpoint for a same backend
- use xPath query instead of sql query
- modify searches endpoint to return a cmHandle object with all public
properties
- handle old (deprecated) queries
- handle public property queries
- create useful examples
- use more verbose error messages
- simplify openapi yamls
- create new query service
- change second endpoint name to a better matched name
- modify legacy tests with new requirements
- create new tests for the new scenarios
