> In OM HA, currently when allocateBlock is called, in applyTransaction() on all OM nodes,
we make a call to SCM and write the allocateBlock information into OM DB. The problem with
this is, every OM allocateBlock and appends new BlockInfo into OMKeyInfom and also this a
correctness issue. (As all OM's should have the same block information for a key, even though
eventually this might be changed during key commit)
>  
> The proposed approach is:
> 1. Calling SCM for allocation of block will happen outside of ratis, and this block information
is passed and writing to DB will happen via Ratis.
