7d8a208a06 ApplicationManager: Avoid deadlocks by killing services once its dependencies have been downloaded, and killing services with handover when it is absolutely necessary
Two cases could've caused deadlocks:
1) Two services use a volume, and one service depends on the other. The volume config changes, but we can't update the volume because we need to kill
both services, and yet we can't kill the dependent service because its dependency isn't ready either.
2) A service with handover strategy uses a volume. The volume config changes. We can't update the volume because the running service is using it, and we can't
start the handover because it depends on the volume being ready. So we need to kill the service to update the volume config.

(Same for networks as with volumes)

cb37f7ebcc ApplicationManager: implement a module to run multicontainer applications
This module takes care of inferring and applying the steps to run multicontainer applications. It will have a Proxyvisor to handle dependent apps and
devices. It understands the relationship between services, networks and volumes to infer the steps in the correct order, also taking update strategies into account.

Changelog-Entry: Allow running docker-compose-like multicontainer applications
