> In OM HA AllocateBlock call where connecting to SCM from OM should not happen

> 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.
