When the vmm process exits abnormally, a goroutine sets s.monitor
to null in the 'watchSandbox' function without getting service.mu,
This will cause another goroutine to block when sending a message
to s.monitor, and it holds service.mu, which leads to a deadlock.
For example, the wait function in the file
.../pkg/containerd-shim-v2/wait.go will send a message to s.monitor
after obtaining service.mu, but s.monitor may be null at this time

Cgroups do not exist on Darwin, so use an empty implementation for
resourcecontrol for the time being. In the process, ensure that the
utilized cgroup handling (ie, isSystemdCgroup) is kept in general file,
since we use this to help assess/constrain the container spec we pass to
the guest.

Some signals may not be defined on non Linux host OSes, like

Moby relies on the prestart hooks to configure network endpoints. We
should rescan the netns after running them so that the newly added
endpoints can be found and plugged to the guest.

The `sev_guest_policy` configuration field distinguishes between SEV and
SEV-ES guests (according to standard AMD SEV policy values).
Modify the kata runtime to detect SEV-ES guests and calculate calculate
the expected launch digest taking into account the number of VCPUs and
their CPU signature (model/family/stepping).

Pass SELinux policy for containers to the agent if `disable_guest_selinux`
is set to `false` in the runtime configuration. The `container_t` type
is applied to the container process inside the guest by default.
Users can also set a custom SELinux policy to the container process using
`guest_selinux_label` in the runtime configuration. This will be an
alternative configuration of Kubernetes' security context for SELinux
because users cannot specify the policy in Kata through Kubernetes's security
context. To apply SELinux policy to the container, the guest rootfs must
be CentOS that is created and built with `SELINUX=yes`.

The containerd stats method and metrics API are broken with Kata 2.5.x, the stats fail to load and the metrics API responds with status code 500
This seems to be down to the conversion from the stats reported by the agent RPC `StatsContainer` where the field `Pagesize` is not
completed by the `setHugetlbStats` method. In the case where multiple sized tables stats are reported, this causes containerd to register two metrics
with the same label set, rather than each being partitioned by the `page` label.
