conman:  Add Frenzy support (wired provisioning).

This uses the FrenzyWifi added in go/fibercl/72780 to observe the
association status of the Frenzy Quantenna module.

This doesn't add support for wireless provisioning, which requires
further Frenzy support in order to get scan results with all necessary
information.
