To work better with Kata containers, we need to delete() from the
OCI runtime as a part of cleanup, to ensure resources aren't
retained longer than they need to be.
To enable this, we need to add a new state to containers,
ContainerStateExited. Containers transition from
ContainerStateStopped to ContainerStateExited via cleanupRuntime
which is invoked as part of cleanup(). A container in the Exited
state is identical to Stopped, except it has been removed from
the OCI runtime and thus will be handled differently when
initializing the container.

We added a timeout for convenience, but most invocations don't
care about it. Refactor it into WaitWithTimeout() and add a
Wait() that doesn't require a timeout and uses the default.

A pause container is added to the pod if the user opts in. The default pause image and command can be overridden. Pause containers are ignored in ps unless the -a option is present. Pod inspect and pod ps show shared namespaces and pause container. A pause container can't be removed with podman rm, and a pod can be removed if it only has a pause container.

This results in some functionality changes:
If a ErrCtrStateInvalid is returned to GetPodStats, the container is ommitted from the stats.
As such, if an empty slice of Container stats are returned to GetPodStats in varlink, an error will occur.
GetContainerStats will return the ErrCtrStateInvalid as well.
Finally, if ErrCtrStateInvalid is returned to the podman stats call, the container will be ommitted from the stats.

The goal is to be very explicit about which functions try to heuristically
guess what is the expected format of the string. Not quite "shaming"
the users, but making sure they stand out.
RFC:
- Is this at all acceptable? Desirable?
- varlink ExportImage says "destination must have transport type";
should it be using alltransports.ParseImageReference
+ PushImageToReference, then?
(While touching the call in cmd/podman, also remove a commented-out
older version of the call.)
Should not change behavior (but does not add unit tests).
