> In this jira, we shall convert all OM related operations to OM HA model,
> which is a 2 step.
> # StartTransaction, where we validate request and check for any errors and
> return the response.
> # ApplyTransaction, where original OM request will have a response which
> needs to be applied to OM DB. This step is just to apply response to Om DB.
> In this way, all requests which are failed with like volume not found or some
> conditions which are not satisfied like when Key not found during rename,
> these all will be executed during startTransaction, and if it fails these
> requests will not be written to raft log also.
