> In OM HA, currently, when openKey is called, in applyTransaction() on all OM nodes,
we make a call to SCM and write the allocateBlock information into OM DB and also clientID
will be generated by each OM node.
>  
> The proposed approach is:
> 1. In startTransaction, call openKey and the response returned should be used to create
a new OmRequest object and used in setting the transaction context. And also modify the ozoneManager
and KeymanagerImpl to handle the code with and without ratis.
>  
> This Jira also implements HDDS-1319.
