BUG-8205: use updated DatastoreContext

DatastoreContext is updated by the config admin overlay, which means
we cannot refer to the initial one passed in when we are deciding
which data store to instantiate.

This fixes up the protocol propagation and adds and initial info about
which protocol is in use.
