VOL-408 First update for this Jira. This update nails down the version
of all containers that have multiple versions. There is one exceptoin
which is the centurylink/ra-certs conatiner that has only one single tag
which is "latest" all others have been nailed to the latest version tag.

Typo in reviewer comments fixed.
