openvswitch: always run handler to to ensure OVS bridges are up

When editing external bridge configuration and running a reconfigure
on openvswitch, handler "Ensuring OVS bridge is properly setup"
needs to run, but doesn't.

This moves the task from handlers to own file and always includes it
after running the handlers.
