To make cgroup v1 and v2 works well, I use `cgroups::cgroup` in
`Container` to manager cgroup now. `CgroupManager` in rustjail has some
drawbacks. Frist, methods in Manager traits are not visiable. So we need
to modify rustjail and make them public. Second, CgrupManager.cgroup is
private too, and it can't be serialized. We can't load/save it in
status file. One solution is adding getter/setter in rustjail, then
create `cgroup` and set it when loading status. In order to keep the
modifications to a minimum in rustjail, I use `cgroups::cgroup`
directly. Now it can work on cgroup v1 or v2, since cgroup-rs do this
stuff.

"An empty [workspace] can be used with a package to conveniently create a
workspace with the package and all of its path dependencies", according
to the https://doc.rust-lang.org/cargo/reference/workspaces.html
This is also matches with the suggestion provided by the Cargo itself,
due to the errors faced with the Cloud Hypervisor CI:
```
10:46:23 this may be fixable by adding `go/src/github.com/kata-containers/kata-containers/src/tools/agent-ctl` to the `workspace.members` array of the manifest located at: /tmp/jenkins/workspace/kata-containers-2-clh-PR/Cargo.toml
10:46:23 Alternatively, to keep it out of the workspace, add the package to the `workspace.exclude` array, or add an empty `[workspace]` table to the package's manifest.

`exec` will execute a command inside a container which exists and is not
frozon or stopped. *Inside* means that the new process share namespaces
and cgroup with the container init process. Command can be specified by
`--process` parameter to read from a file, or from other parameters such
as arg, env, etc. In order to be compatible with `create`/`run`
commands, I refactor libcontainer. `Container` in builder.rs is divided
into `InitContainer` and `ActivatedContainer`. `InitContainer` is used
for `create`/`run` command. It will load spec from given bundle path.
`ActivatedContainer` is used by `exec` command, and will read the
container's status file, which stores the spec and `CreateOpt` for
creating the rustjail::LinuxContainer. Adapt the spec by replacing the
process with given options and updating the namesapces with some paths
to join the container. I also rename the `ContainerContext` as
`ContainerLauncher`, which is only used to spawn process now. It uses
the `LinuxContaier` in rustjail as the runner. For `create`/`run`, the
`launch` method will create a new container and run the first process.
For `exec`, the `launch` method will spawn a process which joins a
container.

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`.

Update the `agent-ctl` docs to show how to use a VSOCK local address
when running the agent and the tool in the same environment. This is an
alternative to using a Unix socket.
Signed-off-by: James O. D. Hunt <james.o.hunt@intel.com>
Unbreak the `agent-ctl` tool connecting to the agent with a Unix domain
socket.
It appears that [1] changed the behaviour of connecting to the agent
using a local Unix socket (which is not used by Kata under normal
operation).
The change can be seen by reverting to commit
72b8144b56 (the one before [1]) and
running the agent manually as:
```bash
$ sudo KATA_AGENT_SERVER_ADDR=unix:///tmp/foo.socket target/x86_64-unknown-linux-musl/release/kata-agent
```
Before [1], in another terminal we see this:
```bash
$ sudo lsof -U 2>/dev/null |grep foo|awk '{print $9}'
@/tmp/foo.socket@
```
But now, we see the following:
```bash
$ sudo lsof -U 2>/dev/null |grep foo|awk '{print $9}'
@/tmp/foo.socket
```
Note the last byte which represents a nul (`\0`) value.
The `agent-ctl` tool used to add that trailing nul but now it seems to not
be needed, so this change removes it, restoring functionality. No
external changes are necessary so the `agent-ctl` tool can connect to
the agent as below like this:
```bash
$ cargo run -- -l debug connect --server-address "unix://@/tmp/foo.socket" --bundle-dir "$bundle_dir" -c Check -c GetGuestDetails
