This change involves:
- Moves ironic-standalone jobs to use 32GB nodes which is a
relatively simple change.
- Changes other jobs excluding multinode jobs to use DIB image
builds by default.
- Changes one of job names to remove tinyipa from the name.
- Also notes a job which can be removed, but removal will be in
a later change... and adds a release note in case anyone looks.
