connect and _connect get an argument start_time that is to be passed to try_connect instead of self.time
Connect helper pushes data twice: once for start_time and once for info.time (if it is not equal to start_time)
Starting time can be passed to component's run(), and is auto-determined if not provided
Basically, only the changes in interfaces.py, schedule.py, component.py and connect_helper.py are of interest.
The rest is fixes for the breaking change to the interface.
