> After the server has been upgraded we will have a client and server side config property that will allow us to rollback the upgrade if required. This config will:
> 1. Continue storing parent column metadata along with a child view 
> 2. Disallow metadata changes to a base table that require being propagated to child views.
> 3. Prevent SYSTEM.CATALOG from splitting.
> If the client is older than the server we also disallow metadata changes to a base table with child views since we no longer lock the parent on the server side. This is handled on the client side as part of PHOENIX-3534.
