The `kata-agent` passes its standard I/O file descriptors
through to the container process that will be launched
by `runk` without manipulation or modification in order to
allow the container process can handle its I/O operations.

In linux 5.14 and hopefully some backports, core scheduling allows processes to
be co scheduled within the same domain on SMT enabled systems.
Containerd impl sets the core sched domain when launching a shim. This
allows a clean way for each shim(container/pod) to be in its own domain and any
additional containers, (v2 pods) be be launched with the same domain as well as
any exec'd process added to the container.

For Kata specifically, we will look for SCHED_CORE environment variable
to be set to indicate we shuold create a new schedule core domain.
This is equivalent to the containerd shim's PR: e48bbe8394Fixes: #4309

Before, we had a mix of slash, etc. Unfortunately, when cleaning URL
paths, serve mux seems to mangle the request method, resulting in each

Add two endpoints: ip6tables, iptables.
Each url handler supports GET and PUT operations. PUT expects

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.

The current implementation of walking the
disks to match with the requested volume path
in agent doesn't work because the volume path
provided by the shim to the agent is the mount
path within the guest and not the device name.
The current logic is trying to match the
device name to the volume path which will never
match.
This change will simplify the
get_volume_capacity_stats and
get_volume_inode_stats to just call statfs and
get the bytes and inodes usage of the volume
path directly.

Today the shim does a translation when doing
direct-volume stats where it takes the source and
returns the mount path within the guest.
The source for a direct-assigned volume is actually
the device path on the host and not the publish
volume path.
This change will perform a lookup of the mount info
during direct-volume stats to ensure that the
device path is provided to the shim for querying
the volume stats.

The go default http mux AFAIK doesn’t support pattern
routing so right now client is padding the url
for direct-volume stats with a subpath of the volume
path and this will always result in 404 not found returned
by the shim.
This change will update the shim to take the volume
path as a GET query parameter instead of a subpath.
If the parameter is missing or empty, then return
400 BadRequest to the client.
