Ralf Haferkamp 43c19966f6 specgen: fix order for setting rlimits
Also make sure that the limits we set for rootless are not higher than
what we'd set for root containers.

Rootless containers failed to start when the calling user already
had ulimit (e.g. on NOFILE) set.

This is basically a cherry-pick of 76f8efc0d0 into specgen

Matthew Heon 644a7b78ff Ensure that containers in pods properly set hostname
When we moved to the new Namespace types in Specgen, we made a
distinction between taking a namespace from a pod, and taking it
from another container. Due to this new distinction, some code
that previously worked for both `--pod=$ID` and
`--uts=container:$ID` has accidentally become conditional on only
the latter case. This happened for Hostname - we weren't properly
setting it in cases where the container joined a pod.
Fortunately, this is an easy fix once we know to check the
condition.

Also, ensure that `podman pod inspect` actually prints hostname.

Fixes #6494

Valentin Rothberg f269be3a31 add {generate,play} kube
Add the `podman generate kube` and `podman play kube` command.  The code
has largely been copied from Podman v1 but restructured to not leak the
K8s core API into the (remote) client.

Both commands are added in the same commit to allow for enabling the
tests at the same time.

Move some exports from `cmd/podman/common` to the appropriate places in
the backend to avoid circular dependencies.

Move definitions of label annotations to `libpod/define` and set the
security-opt labels in the frontend to make kube tests pass.

Implement rest endpoints, bindings and the tunnel interface.

Properly handle default capabilities listed in containers.conf
If user/admin specifies a different list of default capabilties
we need to honor these.

Set up ulimits for rootless containers.
Currently we are setting the maximum limits for rootful podman containers,
no reason not to set them by default for rootless users as well

Matthew Heon 67ec4e1d27 Improve Entrypoint and Command support
We should not be overwriting the Specgen's Command and Entrypoint
when building the final command to pass in the OCI spec. Both of
these will be provided to Libpod for use in `podman inspect` and
committing containers, and both must be set to the user's input,
not overwritten by the image if unset.

Fix this by moving command generation into OCI spec generation
and not modifying the SpecGenerator when we do so.

Matthew Heon 02671a103f Add support for volumes-from, image volumes, init
This should complete Podmanv2's support for volume-related flags.
Most code was sourced from the old pkg/spec implementation with
modifications to account for the split between frontend flags
(volume, mount, tmpfs) and the backend flags implemented here.

Also enables tests for podman run with volumes

Matthew Heon 1cd2b746d0 Modify namespace generation code for specgen
Namespaces have now been changed to properly handle all cases.
Spec handling code for namespaces was consolidated in a single
function.

Still missing:
- Image ports
- Pod namespaces likely still broken in Podmanv2
