Description

The salting code relies on having only a single salt value in each region.
The HBase normalizer doesn't know about this, and will merge regions for salted tables which breaks the salted logic in Phoenix.

I propose explicitly disabling the normalizer on slated tables.

Another solution would be adding something like SplitPolicy for the normalizer, but that requires HBase work first, and does not help with existing HBase versions.
