Implement a simple replica read command
Michael: this has come up again recently so if possible we'd like to get it in a build for testing soon and see about adding it as experimental, if not supported, in 1.1.3.
Moving to .next until it is decided if this will make it into 1.2 or not.
This will be experimental functionality for 1.1
See http://www.couchbase.com/wiki/display/couchbase/Replica+Read for details on implementation.
