Merge 2 'query' end points in NCMP

current endpoints

1. ResponseEntity<CmHandles> executeCmHandleSearch(final Conditions conditions)
2. ResponseEntity<List<String>> queryCmHandles(
   final CmHandleQueryRestParameters cmHandleQueryRestParameters)

as implemented by 

• https://jira.onap.org/browse/CPS-644
• https://jira.onap.org/browse/CPS-731

Required endpoints:

1. ResponseEntity<CmHandles> executeCmHandleSearch(CmHandleQueryRestParameters)
2. ResponseEntity<List<String>> executeCmHandleIdSearch(CmHandleQueryRestParameters)

Component updates:

1. Remove CmHandles definition in docs/openapi/components.yaml (line 166)
2. Create a 'array' of RestOutputCmHandle -> RestOutputCmHandles for endpoint #1 above

The input objects need to be merged into 1 (in OpenAPI components.yaml)

A/C

1. Agree URL for 2 thow (refactored) endpoints with Team
2. Agree single OpenAPI CmHandleQueryRestParameters object for all (future) conditions and agree with team 
3. (demo/CSIT) Two endpoints executing same functionality just different return types
   1. public properties should be included in output for rest endpoint #1

Out-of-Scope

State is not (yet) part of CmHandle response
