> HADOOP-12161 introduced a new {{FileSystem#getStoragePolicy}} call. The DFS implementation
of the call requires two RPC calls, the first to fetch the storage policy ID and the second
to fetch the policy suite to map the policy ID to a {{BlockStoragePolicySpi}}.
> Fix the implementation to require a single RPC call.
