docker-common: fix container restart on new image 

We now look for any excisting containers, if any we compare their
running image with the latest pulled container image.
For OSDs, we iterate over the list of running OSDs, this handles the
case where the first OSD of the list has been updated (runs the new
image) and not the others.

Closes: https://bugzilla.redhat.com/show_bug.cgi?id=1526513
