ovs-workers and ovs-webapp-api not restarted after being killed via ovs-watcher-framework going down

[dejonghb]

On serveral occasions, for some (yet unknown) reason the ovs-watcher-framework goes down (memcache?) which takes along ovs-workers and ovs-webapp-api

After some retries ovs-watcher-framework gets restarted (ovs-watcher-framework.service: Service hold-off time over, scheduling restart) but the ovs-workers and ovs-webapp-api remain inactive.

Filtered syslog attached (hope there's still enough info in there) syslog-filtered.gz
