data_smart: implement remote datastore functionality
This allows you to maintain a local reference to a remote datastore. The
actual implementation of the remote connection is delegated to a
connector object that the caller must define and supply. There is
support for getting variable values and expanding python references
(i.e. ${@...} remotely, however setting variables remotely is not
supported - any variable setting is done locally as if the datastore
were a copy (which it kind of is).
Loosely based on an earlier prototype implementation by Qing He.
