DMI audit support for NCMP: Filter on any properties of CM Handles

• Currently, as part of CPS-1136 - the following REST URL is implemented

 /ncmpInventory/v1/ch/searches

However, for a use-case that when a subsystem is removed from a system, the client would want to access which specific subsystem a cm Handle belongs to and this is only accessible in private properties

Therefore, this user story is to propose an implementation that filters cmHandles with certain properties under a registered dmi-plugin-identifier

Filtering based on private properties:

1. • endpoint (POST):   /ncmpInventory/v1/ch/searches

     {
        additional-properties: [
           {name: xx, value: xx}...
        ]
     }

Questions:

1.  Return type? (object(NcmpServiceCmHandle) or id?)
2. Custom exceptions (wrong structure for req. body?)
    not available (no match) additional-properties or dmi-cm-plugin-identifier = Return: 200 with empty [] – 'no cm handles'

AC:

1.   Demo to team and stakeholders
2.   Testing (unit) Part of Definition-of-Done really
