Support for syncing power supply input history
When a power supply is hotplugged the code will toggle
a GPIO to cause the power supplies to sync their
input history collection. This clears out old values
and restarts measurement at the same time zero.
An external service handles this during a power on.
It doesn't need to be done when the application first
starts because it will either be with power off with
uninteresting power values, and a sync will occur on a
power on anyway, or it was a reboot at runtime where
the power supplies are still synced up anyway.
