Following SystemContext.DockerInsecureSkipTLSVerify, make the
DockerRegistryOne also an OptionalBool, and update callers.
Explicitly document that --tls-verify=true and --tls-verify unset
have different behavior in those commands where the behavior changed
(or where it hasn't changed but the documentation needed updating).
Also make the --tls-verify man page sections a tiny bit more consistent
throughout.
This is a minimal fix, without changing the existing "--tls-verify=true"
paths nor existing manual insecure registry lookups.

Execute the command as described by a container image. The value of the label is processed
into a command by:
1. Ensuring the first argument of the command is podman.
2. Substituting any variables with those defined by the environment or otherwise.

In cases where the image name is more complex like:
quay/baude/alpine_nginx:latest and is not from the docker
registry, we need to be able to run the image by its shortname
such as baude/alpine_nginx. The same goes when the image is
not from a registry but instead has the localhost repository.

We were already writing these to our debug logs. But collecting them
and including them in the error message will make it easier for
callers who don't have debugging enabled to figure out what's going
wrong.
Using multierror gives us both pretty formatting (when we print this
for the user) and programmatic access (for any callers that need to
inspect the constituent errors). With this commit and a config like:
$ cat /etc/containers/registries.conf
[registries.search]
registries = ['registry.access.redhat.com', 'quay.io', 'docker.io']
pulling an unqualified missing image looks like:
$ podman pull does-not/exist
Trying to pull registry.access.redhat.com/does-not/exist:latest...Failed
Trying to pull quay.io/does-not/exist:latest...Failed
Trying to pull docker.io/does-not/exist:latest...Failed
error pulling image "does-not/exist": unable to pull does-not/exist: 3 errors occurred:
* Error determining manifest MIME type for docker://registry.access.redhat.com/does-not/exist:latest: Error reading manifest latest in registry.access.redhat.com/does-not/exist: unknown: Not Found
* Error determining manifest MIME type for docker://quay.io/does-not/exist:latest: Error reading manifest latest in quay.io/does-not/exist: unauthorized: access to the requested resource is not authorized
* Error determining manifest MIME type for docker://does-not/exist:latest: Error reading manifest latest in docker.io/does-not/exist: errors:
denied: requested access to the resource is denied
unauthorized: authentication required
A qualified image looks like:
$ podman pull quay.io/does-not/exist
Trying to pull quay.io/does-not/exist...Failed
error pulling image "quay.io/does-not/exist": unable to pull quay.io/does-not/exist: unable to pull image: Error determining manifest MIME type for docker://quay.io/does-not/exist:latest: Error reading manifest latest in quay.io/does-not/exist: unauthorized: access to the requested resource is not authorized
If one of the searched repositories was offline, you'd get a more
useful routing error for that specific registry. For example:
$ cat /etc/hosts
127.0.0.1 quay.io
$ podman pull does-not/exist
Trying to pull registry.access.redhat.com/does-not/exist:latest...Failed
Trying to pull quay.io/does-not/exist:latest...Failed
Trying to pull docker.io/does-not/exist:latest...Failed
error pulling image "does-not/exist": unable to pull does-not/exist: 3 errors occurred:

pullGoalNamesFromImageReference has been added only to allow testing without
a storage.Store, because I thought that a storage.Store can only be created
by root.
It turns out that non-root stores, at least good enough for reference
parsing and formatting, are possible (and have existed in c/image/storage
tests), so this creates such a store, and modifies the existing
test to test the created c/image/storage.storageReference values
instead of strings; that is more representative, and clearly shows
the impact of further normalization in storageReference (like
defaulting to :latest on NameOnly references).
Eventually we will want to get rid of pullGoalNames / pullRefName.

All callers of LoadFromArchive expect the input to be in the
transport:name format, or create it that way. So, pass a
types.ImageReference instead of a string.
That requires us to add an explicit parse step in (podman pull);
in (podman load) we can, instead of pasting strings, create
native objects directly.
Changes the error behavior of (podman pull), we no longer
try heuristically parsing docker-archive:... inputs as
Docker references.
Also changes the string reported by (podman load) if all parsing
attempts fail, to be only the path instead of dir:path. The error
message itself is likely to be the same (from directory.Transport).

pullImage (now) only uses Image.InputName; it is really used to _create_
