Let me state it more bluntly:  the Templated backend needs to go away.  
There is nothing it does that cannot be done with SQL, and with Dogpile, 
there is not even a performance penalty.

The only benefit I can see to Templated is that the remote systems are 
considered "config files" and then could be kept in Git, but even this 
can be managed by Puppet or a different config manager.

If we are going to keep templated, we should possibly make a "file" 
backend to the Dogpile KVS implementation and use that for Catalog.
