Make sure the DOCKER_SOCK location is accessible by the user when run
rootless. Alos set the DOCKER_HOST env var to ensure docker-compose will
use the non default location. Cleanup steps such as `rm` or `umount`
must be run inside podman unshare otherwise they can fail due missing
privileges.
Change the curl test to use --retry-all-errors otherwise the tests will
flake. The web server inside the container will return http code 500
sometimes, most likely because it is not fully ready to accept
connections. With --retry-all-errors curl will retry instead of failing
and thus the test will work.

With the new rootless cni supporting network connect/disconnect is easy.

Instead of creating an extra container create a network and mount
namespace inside the podman user namespace. This ns is used to
for rootless cni operations.
This helps to align the rootless and rootful network code path.
If we run as rootless we just have to set up a extra net ns and
initialize slirp4netns in it. The ocicni lib will be called in
that net ns.
This design allows allows easier maintenance, no extra container
with pause processes, support for rootless cni with --uidmap
and possibly more.
The biggest problem is backwards compatibility. I don't think
live migration can be possible. If the user reboots or restart
all cni containers everything should work as expected again.
The user is left with the rootless-cni-infa container and image
but this can safely be removed.
To make the existing cni configs work we need execute the cni plugins
in a extra mount namespace. This ensures that we can safely mount over
/run and /var which have to be writeable for the cni plugins without
removing access to these files by the main podman process. One caveat
is that we need to keep the netns files at `XDG_RUNTIME_DIR/netns`
accessible.
`XDG_RUNTIME_DIR/rootless-cni/{run,var}` will be mounted to `/{run,var}`.
To ensure that we keep the netns directory we bind mount this relative
to the new root location, e.g. XDG_RUNTIME_DIR/rootless-cni/run/user/1000/netns
before we mount the run directory. The run directory is mounted recursive,
this makes the netns directory at the same path accessible as before.
This also allows iptables-legacy to work because /run/xtables.lock is
now writeable.

Versions of the ps command have additional spaces between fields, this

Add support for secretRef and secretKeyRef to allow env vars to be set
from a secret. As K8S secrets are dictionaries the secret value must
be a JSON dictionary compatible with the data field of a K8S secret
object. The keys must consist of alphanumeric characters, '-', '_'
or '.', and the values must be base64 encoded strings.

In K8S the pod creation fails if an env var reference a non existing
config map key. It can be marked as optional, but per default it is
mandatory. Podman on the other hand always treat such references as
optional.
Rework envVarsFrom() and envVarValue() to additionaly return an error
and add support for the optional attribute in configMapRef and
configMapKeyRef.

The 'is' check was intended to be called with three arguments,
the last one being a nice helpful test name. There's a fallback
for two-argument calls, but it was a horrible FIXME.
New fallback: the most recently run podman command. We keep
track of it in each run_podman() invocation.
This is not ideal, because it's theoretically possible to
invoke 'is' on something other than the output of run_podman,
but this at least fixes the by-far-most-common case.

the problem so the user doesn't have to guess. For the following pod
spec:
apiVersion: v1
kind: Pod
metadata:
name: mypod
spec:
containers:
- name: myfrontend
image: nginx
volumeMounts:
- mountPath: "/var/www/html"
name: mypd
volumes:
- name: mypd
hostPath:
path: /var/blah
podman will now report:
Error: failed to create volume "mypd": error in parsing HostPath

Remove resize race condition

Since podman-remote resize requests can come in at random times, this
generates a real potential for race conditions. We should only be
attempting to resize TTY on running containers, but the containers can
go from running to stopped at any time, and returning an error to the
caller is just causing noice.
This change will basically ignore requests to resize terminals if the
container is not running and return the caller to success. All other
callers will still return failure.

Ensure manually-created volumes have correct ownership

As part of a fix for an earlier bug (#5698) we added the ability
for Podman to chown volumes to correctly match the user running
in the container, even in adverse circumstances (where we don't
know the right UID/GID until very late in the process). However,
we only did this for volumes created automatically by a
`podman run` or `podman create`. Volumes made by
`podman volume create` do not get this chown, so their
permissions may not be correct. I've looked, and I don't think
there's a good reason not to do this chwon for all volumes the
first time the container is started.
I would prefer to do this as part of volume copy-up, but I don't
think that's really possible (copy-up happens earlier in the
process and we don't have a spec). There is a small chance, as
things stand, that a copy-up happens for one container and then
a chown for a second, unrelated container, but the odds of this
are astronomically small (we'd need a very close race between two
starting containers).

If you are attempting to run a container in interactive mode, and want
a --tty, then there must be a terminal in use.
Docker exits right away when a user specifies to use a --interactive and
--TTY but the stdin is not a tty.
Currently podman will pull the image and then fail much later.
Podman will continue to run but will print an warning message.

Fixes #5788
This commit adds support for named volumes in podman-generate-kube.
Named volumes are output in the YAML as PersistentVolumeClaims.
To avoid naming conflicts, the volume name is suffixed with "-pvc".
This commit adds a corresponding suffix for host path mounts.
Host path volumes are suffixed with "-host".

Validate passed in timezone from tz option

Erik Sjolund reported an issue where a badly formated file
could be passed into the `--tz` option and then the date in the container
would be badly messed up:
```
erik@laptop:~$ echo Hello > file.txt
erik@laptop:~$ podman run --tz=../../../home/erik/file.txt --rm -ti
docker.io/library/alpine cat /etc/localtime
Hello
erik@laptop:~$ podman --version
podman version 3.0.0-rc1
erik@laptop:~$
```
This fix checks to make sure the TZ passed in is a valid
value and then proceeds with the rest of the processing.
This was first reported as a potential security issue, but it
was thought not to be. However, I thought closing the hole
sooner rather than later would be good.
