> In this Jira following things will be implemented:
>  # Make the necessary changes for non-HA code path to use Cache and 
> DoubleBuffer.
>  ## When adding to double buffer, return future. This future will be used in 
> the non-HA path to wait for this, and when it is completed return response to 
> the client.
>  ## Add to double-buffer will happen inside validateAndUpdateCache. In this 
> way, in non-HA, when multiple RPC handler threads are calling preExecute and 
> validateAndUpdateCache, the order inserted in to double buffer will happen in 
> the order requests are received.
>  
> In this Jira, we shall not convert non-ha code path to use this, as security 
> and acl work is not completed to use this new model.
