I've been investigating more into how ostree works and how it relates to
running `ostree container commit` for each layer. I've decided to move
our pre-installed bins and public keys into their own stages and then
bind mount them into a `RUN` instruction so that we can just use `cp` to
get the files into the image and then call `ostree container commit`.
Now all of our layers in the image (after the base image) will be in the
ostree commit tree.
All supported versions of podman, buildah, and docker support the zstd
compression format. This format should allow users to pull less data
when updating their computers.
This fix involves creating a new function for the `BuildDriver` trait
called `build_tag_push`. In order to get the proper logic in place to
make use of `docker buildx`, I had to create a separate function that
would construct the build command to include all of the tags necessary
for pushing. A default implementation of `build_tag_push` will be used
for `podman` and `buildah` which was originally from the build command's
functions. Now that we have custom logic for docker builds, we can take
advantage of using the GitHub cache features without having the `--load`
arg which had a big negative effect on build times. We can now also use
docker for creating local `oci-archive` tarballs for local rebasing.
Making use of the `oci-archive` will require the user to create a
`docker-container` builder as it is not supported on the standard
`docker` builder.

as mentioned here reverting to the bash files module simplifies the
build process (and allows for better usage of `ostree container
commit`). It also means there are less overall layers and (ideally) a
smaller image as a result. Tested locally and template generation seems
to work just fine
the `os_version` is defaulting to the `image_tag` inside containers and
causing our template to use latest tag

Since the command `ostree container commit` checks for the presence of
mounted directories, we will be running it at the end of each module
run. We have also updated the final commit to remove from /tmp/ and
/var/ again in case a user creates extra files through custom
instructions.
Closes#101#95
This separates out the module template logic so that it is easier to
undertstand what each section does. This will also allow creating in
repo documentation for any special modules that don't use a bash base.
