By default skopeo checks to see if the user actually uses one of the
--*tls-verify flags. Their initial value is ignored. Setting the
initial value to false causes Cobra to not display the default value on
the screen when the user runs a `skopeo --help` command.
If the user does not specify a --*tls-verify option, it falls back to
using the value specified in the registries.conf file.

This is the script that runs 'skopeo COMMAND --help' and
cross-checks that all the option flags are documented
in man pages, and vice-versa (all options listed in man
pages appear in COMMAND's --help message).
Copied from podman, with changes for skopeo-land (removing
the rst checks, and conforming to skopeo conventions).

Add new script, hack/man-page-checker, copied from podman. Run it
in 'make validate-local' target.
This is NOT the checker requested in #1332 (verify that flags
listed in 'skopeo foo --help' are documented in man pages and
vice-versa). This is a much simpler script that merely looks
for very basic typos or discrepancies between skopeo.1.md
and skopeo-foo.1.md.
The next part (cross-checking flags) is in progress but will
require a huge number of changes to the man pages. I'm submitting
this now because it's easy to review.

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.

- Improve the language
- Be consistent with the previous example about a trailing slash
- Don't unnecessarily quote :, it is not a shell metacharacter.

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.
