Eduardo Gonzalez 1a682fab28 Support stop specific containers 
With this change, an operator may be able to stop a
service container without stopping all services in a host.
This change is the starting point to start
fast-forward upgrades support.
In next changes new flags will be introducced to disable
stop dataplane services during upgrades.

Implements: blueprint support-stop-containers
