Support list sub-command. It will traverse the root directory, parse
status file and print basic information of containers. Behavior and
print format consistent with runc. To handle race with runk delete
or system user modify, the loop will continue to traverse when errors
are encountered.

runk always launches containers with detached mode,
so users have to use a console socket with run or
create operation when a terminal is used.
If users set `terminal` to `true` in `config.json` and
try to launch a container without specifying a console
socket, runk returns an error with a message early.

This commit enables runk to handle `root.path` in `config.json`
properly even if the path is specified by a relative path that
includes the single (`.`) or the double (`..`) dots.
For example, with a bundle at `/to/bundle` and a rootfs directly
under `/to/bundle` such as `/to/bundle/{bin,dev,etc,home,...}`,
the `root.path` value can be either `/to/bundle` or just `.`.
This behavior conforms to OCI runtime spec.
Accordingly, a bundle path managed by runk's status file
(`status.json`) always is statically stored as a canonical path.
Previously, a bundle path has been got by `oci_state()` of rustjail's
API that returns the path as the parent directory path of a rootfs
(`root.path`). In case of the kata-agent, this works properly because
the kata containers assume that the rootfs path is always
`/to/bundle/rootfs`. However in case of standard OCI runtimes,
a rootfs can be placed anywhere under a bundle, so the rootfs path
doesn't always have to be at a `/to/bundle/rootfs`.

runk uses liboci-cli crate to parse command line options,
but liboci-cli does not support --all option for kill command,
though this is the runtime spec behavior.
But crictl will issue kill --all command when stopping containers,
as a workaround, we use a custom kill command instead of the one
provided by liboci-cli.

The default runtime for io.containerd.runc.v2 is runc,
to use runk, the containerd configuration should set the
default runtime to runk or add BinaryName options for the
runtime.

Add a Rust-based standard OCI container runtime based on
Kata agent.
You can build and install runk as follows:
```sh
$ cd src/tools/runk
$ make
$ sudo make install
$ runk --help
```
