Add basic structure of podman init command

As part of this, rework the number of workers used by various
Podman tasks to match original behavior - need an explicit
fallthrough in the switch statement for that block to work as
expected.

Also, trivial change to Podman cleanup to work on initialized
containers - we need to reset to a different state after cleaning
up the OCI runtime.

+## NAME
+podman\-init - Initialize one or more containers
+
+## SYNOPSIS
+**podman init** [*options*] *container* ...
+
+## DESCRIPTION
+Initialize one or more containers.
+You may use container IDs or names as input.
+Initializing a container performs all tasks necessary for starting the container (mounting filesystems, creating an OCI spec, initializing the container network) but does not start the container.
+If a container is not initialized, the `podman start` and `podman run` commands will do so automatically prior to starting it.
+This command is intended to be used for inspecting or modifying the container's filesystem or OCI spec prior to starting it.
+This can be used to inspect the container before it runs, or debug why a container is failing to run.
+
+## OPTIONS
+
+**--all, a**
+
+Initialize all containers. Containers that have already initialized (including containers that have been started and are running) are ignored.
+
+**--latest, -l**
+Instead of providing the container name or ID, use the last created container. If you use methods other than Podman
+to run containers such as CRI-O, the last started container could be from either of those methods.
+
+The latest option is not supported on the remote client.
