> Add a tool to check rack configuration against EC policies

>
> From testing we have seen setups with problematic racks / datanodes that
> would not suffice basic EC usages. These are usually found out only after the
> tests failed.
> We should provide a way to check this beforehand.
> Some scenarios:
> - not enough datanodes compared to EC policy's highest data+parity number
> - not enough racks to satisfy BPPRackFaultTolerant
> - highly uneven racks to satisfy BPPRackFaultTolerant
> - highly uneven racks (so that BPP's considerLoad logic may exclude some busy
> nodes on the rack, resulting in #2)
