Should report cm handles that have unacceptable alternate ids during registration: create.

1. duplicated in the batch request
2. already in the database for another cm handle.

The current error reporting format:

{     
    "failedCreatedCmHandles": [ "cmHandle": "ch 1", "errorCode": "109","errorText": "cm-handle already exists"}],
    "failedUpdatedCmHandles": [],
    "failedRemovedCmHandles": [],
    "failedUpgradeCmHandles": []
} 

Error Scenarios

Out of scope:

• Invalid Alternate Ids themselves are not part of error response

A/C

1. Both error scenarios shall be tested and demo-ed
2. new error code (111) should be included in the RTD
