--------------------------------------------------------------------
To clarify the intent of this error, should it be its own protocol error
({{CDC_WRITE_FAILURE}}) or should it be a new reason code on {{WRITE_FAILURE}}?
I think if the error only happens on the coordinator node a separate error
may make more sense, but if it can happen on any replica {{WRITE_FAILURE}}
would make more sense as with {{WRITE_FAILURE}} you get a mapping of failed
replicas with their failure codes.
