e10baba326 podman play kube: add containers to pod
when defining containers, we missed the conditional logic to allow
the container to be defined with "WithPod" and so forth.  I had to
slightly modify the createcontainer process to pass a libpod.Pod
that could override things; use nil as no pod.

7ba38b375f createconfig: always cleanup a rootless container
the rootless container storage is always mounted in a different mount
namespace, owned by the unprivileged user.  Even if it is mounted, a
process running in another namespace cannot reuse the already mounted
storage.

Make sure the storage is always cleaned up once the container
terminates.

This has worked with vfs since there is no real mounted storage.

edb285d176 apparmor: apply default profile at container initialization
Apply the default AppArmor profile at container initialization to cover
all possible code paths (i.e., podman-{start,run}) before executing the
runtime.  This allows moving most of the logic into pkg/apparmor.

Also make the loading and application of the default AppArmor profile
versio-indepenent by checking for the `libpod-default-` prefix and
over-writing the profile in the run-time spec if needed.

The intitial run-time spec of the container differs a bit from the
applied one when having started the container, which results in
displaying a potentially outdated AppArmor profile when inspecting
a container.  To fix that, load the container config from the file
system if present and use it to display the data.

43686072d3 Update vendor of runc
Updating the vendor or runc to pull in some fixes that we need.
In order to get this vendor to work, we needed to update the vendor
of docker/docker, which causes all sorts of issues, just to fix
the docker/pkg/sysinfo.  Rather then doing this, I pulled in pkg/sysinfo
into libpod and fixed the code locally.

I then switched the use of docker/pkg/sysinfo to libpod/pkg/sysinfo.

I also switched out the docker/pkg/mount to containers/storage/pkg/mount

75578aad61 add container-init support
Add support for executing an init binary as PID 1 in a container to
forward signals and reap processes.  When the `--init` flag is set for
podman-create or podman-run, the init binary is bind-mounted to
`/dev/init` in the container and "/dev/init --" is prepended to the
container's command.

The default base path of the container-init binary is `/usr/libexec/podman`
while the default binary is catatonit [1].  This default can be changed
permanently via the `init_path` field in the `libpod.conf` configuration
file (which is recommended for packaging) or temporarily via the
`--init-path` flag of podman-create and podman-run.

df99522c67 Fixes to handle /dev/shm correctly.
We had two problems with /dev/shm, first, you mount the
container read/only then /dev/shm was mounted read/only.
This is a bug a tmpfs directory should be read/write within
a read-only container.

The second problem is we were ignoring users mounted /dev/shm
from the host.

If user specified

podman run -d -v /dev/shm:/dev/shm ...

We were dropping this mount and still using the internal mount.

9c359a31d5 create pod on the fly
when a user specifies --pod to podman create|run, we should create that pod
automatically.  the port bindings from the container are then inherited by
the infra container.  this signicantly improves the workflow of running
containers inside pods with podman.  the user is still encouraged to use
podman pod create to have more granular control of the pod create options.

57a8c2e5e8 Mount proper cgroup for systemd to manage inside of the container.
We are still requiring oci-systemd-hook to be installed in order to run
systemd within a container.  This patch properly mounts

/sys/fs/cgroup/systemd/libpod_parent/libpod-UUID on /sys/fs/cgroup/systemd inside of container.

Since we need the UUID of the container, we needed to move Systemd to be a config option of the
container.

d9580ec62b Pass on securityOpts from podInfraContainer to container added to pod.
This is an incomplete fix, as it would be best for the libpod library to be in charge of coordinating the container's dependencies on the infra container. A TODO was left as such. UTS is a special case, because the docker library that namespace handling is based off of doesn't recognize a UTS based on another container as valid, despite the library being able to handle it correctly. Thus, it is left in the old way.
