CMAL is dead, long live CMAL!

What came out of the CMAL effort was a couple things:

1. The dBus interface we have for clustering (takeip, releaseip, entergrace) is 
needed by everyone, no need to make that part pluggable
2. Everyone at the time was using shared storage for client recovery information
3. Clusterized DRC seemed like too big a thing

On the other hand, the pluggable backend for the client recovery information is 
really just part of the CMAL ideas under a new name...
