Cache cleanups only happen if there is a cache miss, and we need to pull a new image
For quay.io/podman/machine-os, we remove all old images from the cache dir. This means we will delete any file that exists in the cache dir; this should be safe to do since the machine pull code should be the only thing touching this cache dir. OCI machine images will always have a different manifest, and won’t be updated with the same manifest, so if the version moves on, there isn’t a reason to keep the old version in the cache, it really doesn’t change.
For Fedora (WSL), we use the cache, so we go through the cache dir and remove any old cached images, on a cache miss. We also switch to using ~/.local/share/containers/podman/machine/wsl/cache as the cache dir rather than ~/.local/share/containers/podman/machine/wsl. Both these behaviors existed in v4.9, but are now added back into 5.x.
For generic files pulled from a URL or a non-default OCI image, we shouldn’t actually cache, so we delete the pulled file immediately after creating a machine image. This restores the behavior from v4.9.
For generic files from a local path, the original file will never be cleaned up
Unsure how to test, so:

For podman machine init, deprecate the --image-path option for --image.
--image now accepts the correct image from containers.conf
Also, add the ability to specify an OCI image from the --image flag using the docker:// transport.

We used to use ignition to perform any customization required for podman
machine because our input was a generic FCOS image. Now that we are
building our own images, some of this customization can be migrated to
the Containerfile itself and be less of a burden in our code at boot up.
At the time of this PR, the Containerfile can be found at
https://github.com/baude/podman-machine-images/tree/main. It is only
present for a so-called daily image. There is little liklihood that
this would the final location for the Containerfile so consider it a
working version only.
Split WSL and rest apart in the e2e tests so we no longer ppull the
generic FCOS image for testing.
Note: the change to the pull image name is so PRs are not immediately
broken that are already in the queue.
