Add/use hack/release.sh script for images
This patch adds a hack/release.sh script and dependencies, and follows the same release practice as CAPV. This changes the location of the container images, mainly splitting the latest builds from master versus a release channel just for releases. A separate doc update needs to be made for this as well.
