Proxyvisor: implement the Proxyvisor for the multicontainer supervisor

This will be quickly replaced by a newer version with a different API, but for now we needed to maintain backwards compatibility (see #508).

This proxyvisor handles dependent apps and devices with a multicontainer parent app.
It also switches to the new update mechanism by inferring and applying updates step by step.
