Description
As discussed on HDFS-7285, StoragePolicy might not be the best name for what StoragePolicy currently is, which is a hardcoded mapping to replica StorageTypes with a fallback, and being able to specify a StorageType for creation vs. replication). Ideally the "policy" is what determines the data temperature in the first place, with the temperature then mapping to the actual StorageTypes to use.
There were a number of suggestions presented, e.g. StorageTag, StoragePolicyTag. Let's figure this out here.
