Docker-compose disable healthcheck properly handled

Previously, if a container had healthchecks disabled in the
docker-compose.yml file and the user did a `podman inspect <container>`,
they would have an incorrect output:
```
"Healthcheck":{
"Test":[
"CMD-SHELL",
"NONE"
],
"Interval":30000000000,
"Timeout":30000000000,
"Retries":3
}
```
After a quick change, the correct output is now the result:
```
"Healthcheck":{
"Test":[
"NONE"
]
}
```
Additionally, I extracted the hard-coded strings that were used for
comparisons into constants in `libpod/define` to prevent a similar issue
from recurring.

envVarValueResourceFieldRef: use int64 for value

assert.Equal() already follows to pointer and compares by value so we
can just directly pass the values. This will make errors much more

Following PR adds support for running containers from a manifest list
present on localstorage. Before this PR podman only supports running
containers from valid images but not from manifest list.
So `podman run -it --platform <some> <manifest-list> command` should
become functional now and users should be able to resolve images on the
bases of provided `--platform` string.
Example
```
podman manifest create test
podman build --platform linux/amd64,linux/arm64 --manifest test .
podman run --rm --platform linux/arm64/v8 test uname -a
```

podman cgroup enhancement
|
| | |
| |
| |
| |
| |
| |

| |
| |

currently, setting any sort of resource limit in a pod does nothing. With the newly refactored creation process in c/common, podman ca now set resources at a pod level
meaning that resource related flags can now be exposed to podman pod create.
cgroupfs and systemd are both supported with varying completion. cgroupfs is a much simpler process and one that is virtually complete for all resource types, the flags now just need to be added. systemd on the other hand
has to be handeled via the dbus api meaning that the limits need to be passed as recognized properties to systemd. The properties added so far are the ones that podman pod create supports as well as `cpuset-mems` as this will
be the next flag I work on.

The nolintlint linter does not deny the use of `//nolint`
Instead it allows us to enforce a common nolint style:
- force that a linter name must be specified
- do not add a space between `//` and `nolint`
- make sure nolint is only used when there is actually a problem

jakecorrenti/restart-privelaged-containers-after-host-device-change
Privileged containers can now restart if the host devices change

If a privileged container is running, stops, and the devices on the host
change, such as a USB device is unplugged, then a container would no
longer start. Previously, the devices from the host were only being
added to the container once: when the container was created. Now, this
happens every time the container starts.
I did this by adding a boolean to the container config that indicates
whether to mount all of the devices or not, which can be set via an option.
During spec generation, if the `MountAllDevices` option is set in the
container config, all host devices are added to the container.
Additionally, a couple of functions from `pkg/specgen/generate/config_linux.go`
were moved into `pkg/util/utils_linux.go` as they were needed in
multiple packages.

volumes
Similar feature was added for named overlay volumes here: https://github.com/containers/podman/pull/12712
Following PR just mimics similar feature for anonymous volumes.
Often users want their anonymous overlayed volumes to be `non-volatile` in nature
that means that same `upper` dir can be re-used by one or more
containers but overall of nature of volumes still have to be overlay
so work done is still on a overlay not on the actual volume.
Following PR adds support for more advanced options i.e custom `workdir`
and `upperdir` for overlayed volumes. So that users can re-use `workdir`
and `upperdir` across new containers as well.
Usage
```console
podman run -it -v /some/path:/data:O,upperdir=/path/persistant/upper,workdir=/path/persistant/work alpine sh
```

pkg/specgen: parse default network mode on server

When podman-remote is used we should not resolve the default network
mode on the client. Defaults should be set on the server. In this case
this is important because we have different defaults for root/rootless.
So when the client is rootless and the server is root we must pick the
root default.
Note that this already worked when --network was set since we did not
parsed the flag in this case. To reproduce you need --network=default.
Also removed a unused function.
[NO NEW TESTS NEEDED] I tested it manually but I am not sure how I can
hook a test like this up in CI. The client would need to run as rootless
and the server as root or the other way around.

podmans remote API does not marshal infra's spec due to
the fact that if it did, all of those options would be available to
the users on the command line. This means we need to manually map "backwards"
some container spec items -> pod spec items before calling PodCreate, this was
one of them that was forgotten

The init binary until now has been bind-mounted to /dev/init which

/run/podman-init. The reasoning for using /run is that it is already

Use the host UID and host GID mapping when building the local pause
image for a Pod with a custom mapping. Otherwise, the mappings are off
and the build fails. Propagating the mapping to the build container is
not needed since the pause image ships merely a copied `catatonit` from
the host.

Add the notion of a "service container" to play kube. A service
container is started before the pods in play kube and is (reverse)
linked to them. The service container is stopped/removed *after*
all pods it is associated with are stopped/removed.
In other words, a service container tracks the entire life cycle
of a service started via `podman play kube`. This is required to
enable `play kube` in a systemd unit file.
The service container is only used when the `--service-container`
flag is set on the CLI. This flag has been marked as hidden as it
is not meant to be used outside the context of `play kube`. It is
further not supported on the remote client.
The wiring with systemd will be done in a later commit.

This commit replaces `ioutil.TempDir` with `t.TempDir` in tests. The
directory created by `t.TempDir` is automatically removed when the test
and all its subtests complete.
Prior to this commit, temporary directory created using `ioutil.TempDir`
needs to be removed manually by calling `os.RemoveAll`, which is omitted
in some tests. The error handling boilerplate e.g.
defer func() {
if err := os.RemoveAll(dir); err != nil {
t.Fatal(err)
}
}
is also tedious, but `t.TempDir` handles this for us nicely.
