Add callback registration in ConnectivityService.

ConnectivityDiagnosticsManager will send callbacks to
ConnectivityService for registering and unregistering them with the
system. ConnectivityService needs to do the processing for persisting
(and deleting) these callbacks on the ConnectivityService Thread, so
messages are sent to the Connectivity Diagnostics  Handler, which runs
on the ConnectivityService Thread.
