New flags in a `podman update` can change the configuration of HealthCheck when the container is started, without having to restart or recreate the container.
This can help determine why a given container suddenly started failing HealthCheck without interfering with the services it provides. For example, reconfigure HealthCheck to keep logs longer than the usual last X results, store logs to other destinations, etc.

This way has a huge disadvantage: The user will not see an error when he
uses a non-existent option. Another disadvantage is, that if we add more
options within podman, they might collide with the names chosen by
plugins. Such issues might be hard to debug.
The advantage is that the usage is very nice:
--network bridge:opt1=val1,opt2=val2.
Alternatively, we could put this behind `opt=`, which is harder to use,
but would solve all issues above:
--network bridge:opt=opt1=val1,opt=opt2=val2

By default today, the container is always started if its pod is also
started. This prevents to create custom with systemd where containers in
a pod could be started through their `[Install]` section.
We add a key `StartWithPod=`, enabled by default, that enables one to
disable that behavior.
This prevents the pod service from changing the state of the container
service.

As documented in the issue there is no way to wait for system units from
the user session[1]. This causes problems for rootless quadlet units as
they might be started before the network is fully up. TWhile this was
always the case and thus was never really noticed the main thing that
trigger a bunch of errors was the switch to pasta.
Pasta requires the network to be fully up in order to correctly select
the right "template" interface based on the routes. If it cannot find a
suitable interface it just fails and we cannot start the container
understandingly leading to a lot of frustration from users.
As there is no sign of any movement on the systemd issue we work around
here by using our own user unit that check if the system session
network-online.target it ready.
Now for testing it is a bit complicated. While we do now correctly test
the root and rootless generator since commit ada75c0bb8 the resulting
Wants/After= lines differ between them and there is no logic in the
testfiles themself to say if root/rootless to match specifics. One idea
was to use `assert-key-is-rootless/root` but that seemed like more
duplication for little reason so use a regex and allow both to make it
pass always. To still have some test coverage add a check in the system
test to ask systemd if we did indeed have the right depdendencies where
we can check for exact root/rootless name match.

These flags can affect the output of the HealtCheck log. Currently, when a container is configured with HealthCheck, the output from the HealthCheck command is only logged to the container status file, which is accessible via `podman inspect`.
It is also limited to the last five executions and the first 500 characters per execution.
This makes debugging past problems very difficult, since the only information available about the failure of the HealthCheck command is the generic `healthcheck service failed` record.
- The `--health-log-destination` flag sets the destination of the HealthCheck log.
- `none`: (default behavior) `HealthCheckResults` are stored in overlay containers. (For example: `$runroot/healthcheck.log`)
- `directory`: creates a log file named `<container-ID>-healthcheck.log` with JSON `HealthCheckResults` in the specified directory.
- `events_logger`: The log will be written with logging mechanism set by events_loggeri. It also saves the log to a default directory, for performance on a system with a large number of logs.
- The `--health-max-log-count` flag sets the maximum number of attempts in the HealthCheck log file.
- A value of `0` indicates an infinite number of attempts in the log file.
- The default value is `5` attempts in the log file.
- The `--health-max-log-size` flag sets the maximum length of the log stored.
- A value of `0` indicates an infinite log length.
- The default value is `500` log characters.

By default wait only waits for the exit of a container, there is really
no way to make it wait for the removal too when the container was
created with --rm. I though I found a clever way in 8a943311db but this
is not working race free. While it works most of the time any other
parallel process might call syncContainer() before the cleanup process
holds the lock until it removes it. As such the wait hack to only update
the state and not sync the exit file did not work so we can drop that.
However the test wants to wait for the removal to happen by the cleanup
process and we can already say --condition=removing to do this but this
will throw an error if the ctr was removed instead of counting this as
success so fix that as well.

In podman-systemd we are intersecting the worlds of containers
and systemd, and I had to stop and think to understand what
`Exec=` does.
I tried to clarify things more here.
I found it especially confusing because the example at the
very top of the file does:
```
Image=quay.io/fedora/fedora
Exec=sleep 10
```
But that only makes sense because the fedora base image
(being generic) doesn't define an `ENTRYPOINT`, just a `CMD`.
But IMO by far the most common usage for podman-systemd
is "app images" which conventionally should use `ENTRYPOINT`
in general. Maybe we should change the default example,
but I'm leaving that for a later followup.
(It perhaps would have been less confusing if this field
had been called `Args=` to make clear it's quite different
in practice from systemd `ExecStart=`)

.build files allow to build an image via Quadlet. The keys from a .build
file are translated to arguments of a `podman build` command by Quadlet.
Minimal keys for .build files are `ImageTag=` and a context directory,
see `SetWorkingDirectory=`, or a `File=` pointing to a Containerfile.
After sorting .build files into the Quadlet dependency order, there
remains a possible dependency cycle issue between .volume and .build
files: A .volume can have `Image=some.build`, and a .build can have
`Volume=some.volume:/some/volume`.
We solve this dependency cycle by prefilling resourceNames with all
image names from .build files before converting all the unit files.
This results in an issue for the test suite though: For .volume's
depending on *.image or *.build, we need to copy these additional
dependencies to the test's quadletDir, otherwise the test will fail.
This is necessary, because `handleImageSource()` actually needs to know
the image name defined in the referenced *.{build,image} file. It cannot
fall back on the default names, as it is done for networks or volumes,
for example.

When an empty volume is mounted into a container, Docker will
chown that volume appropriately for use in the container. Podman
does this as well, but there are differences in the details. In
Podman, a chown is presently a one-and-done deal; in Docker, it
will continue so long as the volume remains empty. Mount into a
dozen containers, but never add content, the chown occurs every
time. The chown is also linked to copy-up; it will always occur
when a copy-up occurred, despite the volume now not being empty.
This PR changes our logic to (mostly) match Docker's.
For some reason, the chowning also stops if the volume is chowned
to root at any point. This feels like a Docker bug, but as they
say, bug for bug compatible.
In retrospect, using bools for NeedsChown and NeedsCopyUp was a
mistake. Docker isn't actually tracking this stuff; they're just
doing a copy-up and permissions change unconditionally as long as
the volume is empty. They also have the two linked as one
operation, seemingly, despite happening at very different times
during container init. Replicating that in our stateful system is
nontrivial, hence the need for the new CopiedUp field. Basically,
we never want to chown a volume with contents in it, except if
that data is a result of a copy-up that resulted from mounting
into the current container. Tracking who did the copy-up is the
easiest way to do this.

Effectively, this is an ability to take an image already pulled
to the system, and automatically mount it into one or more
containers defined in Kubernetes YAML accepted by `podman play`.
Requirements:
- The image must already exist in storage.
- The image must have at least 1 volume directive.
- The path given by the volume directive will be mounted from the
image into the container. For example, an image with a volume
at `/test/test_dir` will have `/test/test_dir` in the image
mounted to `/test/test_dir` in the container.
- Multiple images can be specified. If multiple images have a
volume at a specific path, the last image specified trumps.
- The images are always mounted read-only.
- Images to mount are defined in the annotation
"io.podman.annotations.kube.image.automount/$ctrname" as a
semicolon-separated list. They are mounted into a single
container in the pod, not the whole pod.
As we're using a nonstandard annotation, this is Podman only, any
Kubernetes install will just ignore this.
Underneath, this compiles down to an image volume
(`podman run --mount type=image,...`) with subpaths to specify
what bits we want to mount into the container.
Signed-off-by: Matt Heon <mheon@redhat.com>
Image volumes (the `--mount type=image,...` kind, not the
`podman volume create --driver image ...` kind - it's strange
that we have two) are needed for our automount scheme, but the
request is that we mount only specific subpaths from the image
into the container. To do that, we need image volume subpath
support. Not that difficult code-wise, mostly just plumbing.
Also, add support to the CLI; not strictly necessary, but it
doesn't hurt anything and will make testing easier.

The logic here is more complex than I would like, largely due to
the behavior of `podman inspect` for running containers. When a
container is running, `podman inspect` will source as much as
possible from the OCI spec used to run that container, to grab
up-to-date information on things like devices. We don't want to
change this, it's definitely the right behavior, but it does make
updating a running container inconvenient: we have to rewrite the
OCI spec as part of the update to make sure that `podman inspect`
will read the correct resource limits.
Also, make update emit events. Docker does it, we should as well.
