reportErrors property

Partial failures, one for each Operation in the request that failed processing.

There are three possible combinations of the RPC status: 1. The combination of a successful RPC status and an empty report_errors list indicates a complete success where all Operations in the request are processed successfully. 2. The combination of a successful RPC status and a non-empty report_errors list indicates a partial success where some Operations in the request succeeded. Each Operation that failed processing has a corresponding item in this list. 3. A failed RPC status indicates a general non-deterministic failure. When this happens, it's impossible to know which of the 'Operations' in the request succeeded or failed.
