Properly document what should be done with dockerhub's arvados/jobs:latest image from 2 years ago
It is expected for some time now that workflow developers base their container images from specific version tags of the
arvados/jobs image, nevertheless we still have the
latest tag in DockerHub and it's pointing to a really old image.
We should review the current documentation and make the appropriate updates to let users know that the
latest tag shouldn't be used and it's there for legacy support purposes.
Also, we'll probably want to come up with a deprecation plan for it.
