the combination --pod and --userns is already blocked. Ignore the
PODMAN_USERNS variable when a pod is used, since it would cause to
create a new user namespace for the container.
Ideally a container should be able to do that, but its user namespace
must be a child of the pod user namespace, not a sibling. Since
nested user namespaces are not allowed in the OCI runtime specs,
disallow this case, since the end result is just confusing for the
user.

Add --restart flag to pod create to allow users to set the
restart policy for the pod, which applies to all the containers
in the pod. This reuses the restart policy already there for
containers and has the same restart policy options.
Add "never" to the restart policy options to match k8s syntax.
It is a synonym for "no" and does the exact same thing where the
containers are not restarted once exited.
Only the containers that have exited will be restarted based on the
restart policy, running containers will not be restarted when an exited
container is restarted in the same pod (same as is done in k8s).

Currently Podman prevents SELinux container separation,
when running within a container. This PR adds a new
--security-opt label=nested
When setting this option, Podman unmasks and mountsi
/sys/fs/selinux into the containers making /sys/fs/selinux
fully exposed. Secondly Podman sets the attribute
run.oci.mount_context_type=rootcontext
This attribute tells crun to mount volumes with rootcontext=MOUNTLABEL
as opposed to context=MOUNTLABEL.
With these two settings Podman inside the container is allowed to set
its own SELinux labels on tmpfs file systems mounted into its parents
container, while still being confined by SELinux. Thus you can have
nested SELinux labeling inside of a container.

we were previously using an experimental feature in crun, but we lost
this capability once we moved to using the OCI runtime spec to specify
the volume mappings in fdcc2257df0fb0cb72d3fbe1b5aa8625955e1219.
Add the same feature to libpod, so that we can support relative
positions for the idmaps.

Now that the OCI runtime specs have support for idmapped mounts, let's
use them instead of relying on the custom annotation in crun.
Also add the mechanism to specify the mapping to use. Pick the same
format used by crun so it won't be a breaking change for users that
are already using it.

The remote client should be allowed to specify if the container should
be run with the proxy env vars. It will still use the proxy vars from
the server process and not the client. This makes podman-remote more
consistent with the local version and easier to use in environments
where a proxy is required.

Startup healthchecks are similar to K8S startup probes, in that
they are a separate check from the regular healthcheck that runs

Since pasta is now considered a network mode using it as network name
causes a conflict. For now we will prefer the named network but in a
future major version bump we want to remove this and just use pasta(1).
The docs should reflect that this name is considered deprecated.

Conceptually equivalent to networking by means of slirp4netns(1),
with a few practical differences:
- pasta(1) forks to background once networking is configured in the
namespace and quits on its own once the namespace is deleted:
file descriptor synchronisation and PID tracking are not needed
- port forwarding is configured via command line options at start-up,
instead of an API socket: this is taken care of right away as we're
about to start pasta
- there's no need for further selection of port forwarding modes:
pasta behaves similarly to containers-rootlessport for local binds
(splice() instead of read()/write() pairs, without L2-L4
translation), and keeps the original source address for non-local
connections like slirp4netns does
- IPv6 is not an experimental feature, and enabled by default. IPv6
port forwarding is supported
- by default, addresses and routes are copied from the host, that is,
container users will see the same IP address and routes as if they
were in the init namespace context. The interface name is also
sourced from the host upstream interface with the first default
route in the routing table. This is also configurable as documented
- sandboxing and seccomp(2) policies cannot be disabled
- only rootless mode is supported.
See https://passt.top for more details about pasta.
Also add a link to the maintained build of pasta(1) manual as valid
in the man page cross-reference checks: that's where the man page
for the latest build actually is -- it's not on Github and it doesn't
match any existing pattern, so add it explicitly.
