This also includes a new `login` command. The signing and CI logic is now using the Driver trait system along with a new experimental sigstore signing driver. New static macros have also been created to make implementation management easier for `Command` usage and `Driver` trait implementation calls.

This will be used for running containers for various tasks. There will
be a way to take all output from the process and a way to display output
from a running container like our builds have.
### Buildah/Podman support
Buildah and podman can make heavy use of the squash feature. Something
that I've noticed when trying to build from inside of a container,
requiring intermediate layers with mounts causes build times to
skyrocket. Build times are much faster when using the `--squash`
functionality (seen as `--layers=false`).
Here are the following results from my personal build using both squash
and non-squash functionality.
#### Squash upgrade:
```
$> rpm-ostree upgrade
Pulling manifest: ostree-image-signed:docker://registry.gitlab.com/wunker-bunker/wunker-os/jp-laptop
Importing: ostree-image-signed:docker://registry.gitlab.com/wunker-bunker/wunker-os/jp-laptop (digest: sha256:60f743ba322041918d302e7e7f10438c59502e19343c294064bacb676c8eb7b7)
ostree chunk layers already present: 65
custom layers already present: 3
custom layers needed: 1 (814.0 MB)
```
All changes appear to show as a single custom layer. Any small change
even at the end of the build appears to require completely downloading
the new layer (squash only squashes additional layers on top of the base
layer). This makes sense as layers cannot currently be downloaded by
diff.
#### Non-squash upgrade:
```
$> rpm-ostree upgrade
Pulling manifest: ostree-image-signed:docker://registry.gitlab.com/wunker-bunker/wunker-os/jp-desktop-gaming:latest
Importing: ostree-image-signed:docker://registry.gitlab.com/wunker-bunker/wunker-os/jp-desktop-gaming:latest (digest: sha256:0658b51febfcbaa1722961b7a6d2b197d3823a6228e330f45dd1e1aaefd145c5)
ostree chunk layers already present: 65
custom layers already present: 4
custom layers needed: 15 (942.4 MB)
```
As expected, there are more layers when not squashing and the size is
slightly bigger. Most likely due to there being extra information stored
in the layers that is subsequently removed.
### Docker support
Docker is apparently [no longer
supporting](https://github.com/docker/buildx/issues/1287) the use of the
`--squash` arg. The use of squash will not be available for the docker
driver in this case.
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.
