implement API method #1 from https://wiki.onap.org/display/DW/CPS-390+Spike%3A+Define+and+Agree+DMI+Plugin+REST+Interface#CPS390Spike:DefineandAgreeDMIPluginRESTInterface-DMIInventory,Model&DataSyncAPI

including REST and Service Layer

A/C

Update yaml to create an endpoint for registration in NCMP

Deprecate 'old' (defined in H) methods in Open API 
accept properties in json format
Agree and implement error scenarios
Keep track of error scenarios in a separate table https://wiki.onap.org/display/DW/CPS+Exceptions+and+REST+API+HTTP+Response+Codes
An error will tell the DMI Plugin that this datasource has already been processed - no need to recover the cmhandles again.
Store cmhandle name and cmhandle id and additional properties within the db from the ri module
Use java service api in cps
Write groovy tests
Verify registration is successful by showing the data in the db
Demo to team using a deployment that has cps core and ncmp

Naming Suggestions

• REST endpoint data object : dmiPluginRestration { dmiPlugin, createdCmHandles[ {cmHandle, additonalProperties[]] }

  (as per body on 390 study)

• Java API can use similar object;  updateDmuiPluginRegsitration(dmiPLuginRegistration)
