View source for Automatic updates on bridge instance delete

When a bridge instance is deleted from a bridge, observation production configuration and reasoners that become obsolete are automatically deleted
* If the instance being deleted is the last instance of that thing type included in the bridge instance list, any observation production configuration for that thing type is automatically deleted from the bridge
* Any reasoner action that sends a command to that instance is automatically deleted.
** The action may be in the same bridge or in any other bridge of the same tenant
** If the action deleted is the only one included in the reasoner, the reasoner is also deleted
* Actions to be deleted are only those that send commands to the instance and that belong to bridges of the same tenant. This takes into account that commands cannot be sent between bridges of different tenants
