ask pyro group config questions for all-in-one config site when pyro is enabled
in serverctl.py, the pyro questions are not asked for all-in-one configs,
because this is webctl.py's responsibility. However for a all-in-one instance,
repo_method is "in-memory" so the pyro questions would not be asked even if
pyro had been explicitely enabled before.
