This replicates the --all copy flag to sync to perform the same
behavior. Namely, the default is CopySystemImage unless --all is passed
which changes the behavior to CopyAllImages. While it is probably
desirable for --all to be the default as there is no option to override
ones architecture with the sync command, --all can potentially break
existing sync incantations depending on registry support. Hence
CopySystemImage remains the default.

a containers-storage: source, which might not even work all that
well with all the automatic defaults Podman sets up.

Fields that magically change their behavior depending on type of the value
are too much hassle for no benefit.
For now, this just copies&pastes the full loop in imagesToCopyFromRegistry
to create another loop handling the new ImagesByTagRegex field. Simplifications
to reduce duplication will follow.

With additional prefixed flags for authfiles, it is possible to override the shared authfile flag to use different authfiles for src and dest registries. This is an important feature if the two registries have the same domain (but different paths) and require separate credentials.
Closes#773.

The skopeo sync command can sync images between a SOURCE and a
destination.
The purpose of this command is to assist with the mirroring of
container images from different docker registries to a single
docker registry.
Right now the following source/destination locations are implemented:
* docker -> docker
* docker-> dir
* dir -> docker
The dir location is supported to handle the use case
of air-gapped environments.
In this context users can perform an initial sync on a trusted machine
connected to the internet; that would be a `docker` -> `dir` sync.
The target directory can be copied to a removable drive that can then be
plugged into a node of the air-gapped environment. From there a
`dir` -> `docker` sync will import all the images into the registry serving
the air-gapped environment.
Notes when specifying the `--scoped` option:
The image namespace is changed during the `docker` to `docker` or `dir` copy.
The FQDN of the registry hosting the image will be added as new root namespace
of the image. For example, the image `registry.example.com/busybox:latest`
will be copied to
`registry.local.lan/registry.example.com/busybox:latest`.
The image namespace is not changed when doing a
`dir:` -> `docker` sync operation.
The alteration of the image namespace is used to nicely scope images
coming from different registries (the Docker Hub, quay.io, gcr,
other registries). That allows all of them to be hosted on the same
registry without incurring in clashes and making their origin explicit.

Add a --all/-a flag to instruct us to attempt to copy all of the
instances in the source image, if the source image specified to "skopeo
copy" is actually a list of images. Previously, we'd just try to locate
one for our preferred OS/arch combination.
Add a couple of tests to verify that we can copy an image into and then
back out of containers-storage. The contents of an image that has been
copied out of containers-storage need a bit of tweaking to compensate
for containers-storage's habit of returning uncompressed versions of the
layer blobs that were originally written to it, in order to be
comparable to the image as it was when it was pulled from a registry.
