When running a Packer build which is based on a "fat image", ansible-init runs during boot of the Packer build VM. This is undesirable as:

In the general case it may take actions which are not appropriate during a build
When ansible-init completes it writes its sentinel file into the resulting image, which means booting a cluster instance using the resulting image never runs ansible-init

This PR disables ansible-init during packer builds via a metadata flag.

@wtripp180901 can you update from main please?

Latest image tested by:

New fat image built
'extra' build on top of it
mount that image to make sure ansible-init hasn't run during the second fatimage build
then launch the image in a VM to make sure the sentinel file is written
