Cleaning up the OCI runtime is not allowed in the Removing state.
To ensure it is actually cleaned up, when calling cleanup() as
part of removing a container, do so before we set the Removing
state, so we can successfully remove.

Theoretically these should never happen, but it never hurts to be
sure and check. Add a check to one, make the other one a
create-if-not-exist (it was just adding, not checking the
contents).

Some runtimes (e.g. Kata containers) seem to object to having us
unmount storage before the container is removed from the runtime.
This is an easy fix (change the order of operations in cleanup)
and seems to make more sense than the way we were doing things.

We’re now able to build a static podman binary based on a custom nix
derivation. This is integrated in cirrus as well, whereas a later target
would be to provide a self-contained static binary bundle which can be
installed on any Linux x64-bit system.

I realized that setting NetworkMode to private when we are making
a network namespace but not configuring it with CNI or Slirp is
wrong; that's considered `--net=none` not `--net=private`. At the
same time, realized that we actually store whether Slirp is in
use, so we can be more specific than just "default" and instead
say slirp4netns or bridge.

This one was a massive pain to track down.
The original symptom was an error message from rootless Podman
trying to make a container in a pod. I unfortunately did not look
at the error message closely enough to realize that the namespace
in question was the cgroup namespace (the reproducer pod was
explicitly set to only share the network namespace), else this
would have been quite a bit shorter.
I spent considerable effort trying to track down differences
between the inspect output of the two containers, and when that
failed I was forced to resort to diffing the OCI specs. That
finally proved fruitful, and I was able to determine what should
have been obvious all along: the container was joining the cgroup
namespace of the infra container when it really ought not to
have.
From there, I discovered a variable collision in pod config. The
UsePodCgroup variable means "create a parent cgroup for the pod
and join containers in the pod to it". Unfortunately, it is very
similar to UsePodUTS, UsePodNet, etc, which mean "the pod shares
this namespace", so an accessor was accidentally added for it
that indicated the pod shared the cgroup namespace when it really
did not. Once I realized that, it was a quick fix - add a bool to
the pod's configuration to indicate whether the cgroup ns was
shared (distinct from UsePodCgroup) and use that for the
accessor.
Also included are fixes for `podman inspect` and
`podman pod inspect` that fix them to actually display the state
of the cgroup namespace (for container inspect) and what
namespaces are shared (for pod inspect). Either of those would
have made tracking this down considerably quicker.

If the first time you run podman in a user account you do a
su - USER, and the second time, you run as the logged in USER
podman fails, because it is not handling the tmpdir definition
in the database. This PR fixes this problem.

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.

There is a potential of a race condition where
a container is removed while podman is looking
up information on the total containers. This can
cause podman info to fail with an error
"no such container".
This change ignores the failure.

Signed-off-by: baude <bbaude@redhat.com>
Continue the refactoring of image removal. I didn't manage to break all
the following changes into smaller and easier to digest commits due to
time constraints:
* Return an error slice instead of a single error. Use multierror only
in the client/frontend. Reflect that in the types.
* Use the batch image removal in the client while preserving the more
rest-idiomatic single-image removal endpoint.
* Add a new handler for the single-image removal endpoint to make it
share the same code as the batch endpoint.
* Expose bindings for the single and batch endpoints, so we can
properly test them.
* Add several convenience functions for error handling to
pkg/errorhandling.
* Set the correct error type in libpod to set the exit code to 2 when
one or more containers are using an image.
* Massage the bindings tests a bit and tackle compilation errors.

The length and size of our error messages on failure to pull
is huge. This patch at least eliminates some of the wrapping.
But I think eventually we need to look at containers/image

more human friendly.
