One of the side-effects of the `--userns=keep-id` command is
switching the default user of the container to the UID of the
user running Podman (though this can still be overridden by the
`--user` flag). However, it did this by setting the UID and GID
in the OCI spec, and not by informing Libpod of its intention to
switch users via the `WithUser()` option. Because of this, a lot
of the code that should have triggered when the container ran
with a non-root user was not triggering. In the case of the issue
that this fixed, the code to remove capabilities from non-root
users was not triggering. Adjust the keep-id code to properly
inform Libpod of our intention to use a non-root user to fix
this.
Also, fix an annoying race around short-running exec sessions
where Podman would always print a warning that the exec session
had already stopped.

If a user only has a local dns server in the resolv.conf file the dns
resolution will fail. Instead we create a new resolv.conf which will use
the slirp4netns dns.

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.

For rootless users the infra container used the slirp4netns net mode
even when bridge was requested. We can support bridge networking for
rootless users so we have allow this. The default is not changed.

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.
