> 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.
