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=`)

Adds a `NetworkAlias=` key to both .container and .pod quadlet files,
which translates to the `--network-alias` option to `podman run` and
`podman pod create` respectively. Can be repeated multiple times.

I found that Quadlet didn't currently have support for log options.
This merge allows Quadlet to handle log options and correctly
pass those values through to `podman run` for Container and Kube
types.
Syntactically consistent with existing parameters:
```ini
[Container]
Image=localhost/imagename
LogOpt=path=/var/log/container/mycontainer.json
LogOpt=size=10mb
```

.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.

If a container unit starts on boot with a dependency on `default.target`
the image unit may start too soon, before network is ready. This cause
the unit to fail to pull the image.
- Add a dependency on `network-online.target` to make sure image pulls
don't fail.
See https://github.com/containers/podman/issues/21873
- Document the hardcoded dependency on `network-online.target` for images unit
and explain how it can be overriden if necessary.

New CI validation check: all keys in quadlet.go must be
documented at least once in podman-systemd.unit.5.md.
Adding '// deprecated' next to an enum definition will
exclude said key from the documentation cross-checks.
And, because the md file lists keys in both table and block
form, make sure those all match.
And make sure everything is sorted in lexical order, in
both .go source and in man page.
And add a validation check to make sure it stays that way.

The quotes are interpreted as part of the value, so that, for example,
`HealthCmd="true"` is translated to the podman argument
`--health-cmd "\"true\""`.

When the `Mask=` and `Unmask=` quadlet options were initially added,

For a source file like `foo.container`, look for drop in named
`foo.container.d/*.conf` and merged them into the main file. The
dropins are applied in alphabetical order, and files in earlier
diretories override later files with same name.
This is similar to how systemd dropins work, see:
