In lipod, we now log major events that occurr. These events
can be displayed using the `podman events` command. Each
event contains:
* Type (container, image, volume, pod...)
* Status (create, rm, stop, kill, ....)
* Timestamp in RFC3339Nano format
* Name (if applicable)
* Image (if applicable)
The format of the event and the varlink endpoint are to not
be considered stable until cockpit has done its enablement.

Add the ability to manually run a container's healthcheck command.
This is only the first phase of implementing the healthcheck.
Subsequent pull requests will deal with the exposing the results and

Image.MatchRepoTag and findImageInRepoTags do some kind of
heuristic search; the motivation and design of both, and how they
should deal with digests, is not obvious to me.
Instead of figuring that out now, just factor it out into a
scary-named method and leave the "tag" value (with its "latest"/"none"
value) alone.
Similarly, the .registry and .name fields should typically not be used;
users should use either hasRegistry or normalized reference types;
so, isolate the difficult-to-understand search code, and computation
of these values, into this new search-specific helper.
Should not change behavior.

Again, rely on the official API, instead of the suprising "suspiciousTagValueForSearch"
value (set to :latest on untagged images, and :none on digested ones!)
CHANGES BEHAVIOR, but the previous output of normalization of digested values was
not even syntatically valid, so this can't really be worse.
Still, maybe we should refuse to tag with digested references in the first place.

Now that DecomposeString has no users, make the type private again.
Any new users of it should come with a rationale - and new users
of the "none"/"latest" handling of untagged/digested names that is
currently implemented should have an exceptionaly unusual rationale.

Avoid generating
quay.io/openshift-release-dev/ocp-release@sha256@sha256:239... and
similar when the image name is already digest-based [1]. It's not
clear exactly how we get into this state, but as shown by the unit
tests, the new code handles this case correctly (while the previous
code does not).

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.

Add an exists subcommand to podman container and podman image that allows

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.
If no label exists in the container image, nothing is done.

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.

FINALLY, (podman load) can pass through an ImageReference directly from

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).

All callers of getCopyOptions also call GetSystemContext with the same three parameters;
we will want to simplify this by passing the first SystemContext to getCopyOptions,
which can then inherit this data instead of so many parameters everywhere.

pullImage (now) only uses Image.InputName; it is really used to _create_
an Image object, based on the pull results (as is most visible in the
LoadFromArchive caller), so it should not be a method on it.
This also simplifies a bit the number of different kids of uses of
Image.InputName; still apparently not enough to clearly document
the field, though.

(... but keep it in DefaultTransport, which remains irregular.)
This makes DockerTransport consistent with the others, and much more importantly,
allows several instances to do
> imgRef.Transport().Name() == DockerTransport
instead of the current
> strings.HasPrefix(DockerTransport, imgRef.Transport().Name())
, which currently works but is pretty nonsensical (it does not check
the "docker://" prefix against the _full reference_, but it checks
the _transport name_ as a prefix of "docker://", i.e. a transport named
"d" would be accepted.
Should not change behavior, because the only currently existing transport
which has a name that is a prefix of "docker://" is c/image/docker.Transport
(but does not add unit tests).
