> PHOENIX-2051 introduced new Parent-Child linking rows to System.Catalog that speed up
view deletion. Unfortunately, this breaks assumptions in PHOENIX-3639, which gives a way to
replicate tenant views from one cluster to another. (It assumes that all the metadata for
a tenant view is owned by the tenant -- the linking rows are not.) 
> PHOENIX-3639 was a workaround in the first place to the more fundamental design problem
that Phoenix places the metadata for both table schemas -- which should never be replicated
-- in the same table and column family as the metadata for tenant views, which should be replicated.

> Note that the linking rows also make it more difficult to ever split these two datasets
apart, as proposed in PHOENIX-3520.
