Move ClusterAdminRpcService to its own bundle
The ClusterAdminRpcService can't be instantiated with the clustered
datastore blueprint xml b/c it needs the binding RPC registry service so
I moved it to its own bundle.
I made the ClusterAdminProviderModule a no-op since the
ClusterAdminRpcService is now created via blueprint.
I also had to export some packages from the sal-distributed-datastore
bundle.
