> SA1019: rand.Seed has been deprecated since Go 1.20 and an alternative

>a specific sequence of results from the global random source (using
>functions such as Int) can be broken when a dependency changes how
>much it consumes from the global random source. To avoid such breakages,

Add a common NRI 'service' plugin. It takes care of relaying
requests and respones to and from NRI (external NRI plugins)
and the high-level containerd namespace-independent logic of
applying NRI container adjustments and updates to actual CRI
and other containers.
The namespace-dependent details of the necessary container
manipulation operations are to be implemented by namespace-
specific adaptations. This NRI plugin defines the API which
such adaptations need to implement.

golang.org/x/sys/windows now implements this, so we can use that
instead of a local implementation.

The `IsAnInteractiveSession` was deprecated, and `IsWindowsService` is marked
as the recommended replacement.
For details, see 280f808b4a
> CL 244958 includes isWindowsService function that determines if a
> process is running as a service. The code of the function is based on
> public .Net implementation.
>
> IsAnInteractiveSession function implements similar functionality, but

> as code written by Microsoft for their official product.
>
> This change copies CL 244958 isWindowsService function into svc package
> and makes it public. The intention is that future users will prefer
> IsWindowsService to IsAnInteractiveSession.

Previously we were reassigning os.Stderr to the panic.log file we create
when getting asked to run Containerd as a Windows service. The panic.log
file was used as a means to easily collect panic stacks as Windows
services don't have regular standard IO, and the usual recommendation
is to either write to the event log or just to a file in the case of
running as a service.
One place where this panic.log flow was biting us was with shim logging,
which is forwarded from the shim and copied to os.Stderr directly which was
causing shim logs to get forwarded to this panic.log file instead of just
panics. We expose an additional `--log-file` flag if you ask to run a
windows service which is the main way you'd get Containerd logs, and with
this change all of the shim logging which would today end up in panic.log
will now also go to this log file.

Create lease plugin type to separate lease manager from services plugin.
This allows other service plugins to depend on the lease manager.

In linux 5.14 and hopefully some backports, core scheduling allows processes to
be co scheduled within the same domain on SMT enabled systems.
The 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.
