timeout the mycroft connection if its not available for more than some minutes

When mycroft integration is enabled the containment expects a connection the assistant message-bus, but there can be circumstance where the assistant has failed to load, so lets not hold up trying to establish a connection any longer than the average time needed for Mycroft/OVOS to finish booting. If it passes this threshold then its safe to assume the assistant failed to load and we should stop trying to connect and disable the mycroft status indicator.
