Previously, we assumed that TriggerShutdown() should never be called from vendor_init and used property service as a back up in case it ever did. We have since then found out that vendor_init may indeed call TriggerShutdown() and we want to make it just as strict as it is in init, wherein it will immediately start the shutdown sequence without executing any further commands. Test: init unit tests, trigger shuttdown from init and vendor_init Change-Id: I1f44dae801a28269eb8127879a8b7d6adff6f353
