John Howard 85ad4b16c1 Windows: Experimental: Allow containerd for runtime
Signed-off-by: John Howard <jhoward@microsoft.com>

This is the first step in refactoring moby (dockerd) to use containerd on Windows.
Similar to the current model in Linux, this adds the option to enable it for runtime.
It does not switch the graphdriver to containerd snapshotters.

 - Refactors libcontainerd to a series of subpackages so that either a
  "local" containerd (1) or a "remote" (2) containerd can be loaded as opposed
  to conditional compile as "local" for Windows and "remote" for Linux.

 - Updates libcontainerd such that Windows has an option to allow the use of a
   "remote" containerd. Here, it communicates over a named pipe using GRPC.
   This is currently guarded behind the experimental flag, an environment variable,
   and the providing of a pipename to connect to containerd.

 - Infrastructure pieces such as under pkg/system to have helper functions for
   determining whether containerd is being used.

(1) "local" containerd is what the daemon on Windows has used since inception.
It's not really containerd at all - it's simply local invocation of HCS APIs
directly in-process from the daemon through the Microsoft/hcsshim library.

(2) "remote" containerd is what docker on Linux uses for it's runtime. It means
that there is a separate containerd service running, and docker communicates over
GRPC to it.

To try this out, you will need to start with something like the following:

Window 1:
	containerd --log-level debug

Window 2:
	$env:DOCKER_WINDOWS_CONTAINERD=1
	dockerd --experimental -D --containerd \\.\pipe\containerd-containerd

You will need the following binary from github.com/containerd/containerd in your path:
 - containerd.exe

You will need the following binaries from github.com/Microsoft/hcsshim in your path:
 - runhcs.exe
 - containerd-shim-runhcs-v1.exe

For LCOW, it will require and initrd.img and kernel in `C:\Program Files\Linux Containers`.
This is no different to the current requirements. However, you may need updated binaries,
particularly initrd.img built from Microsoft/opengcs as (at the time of writing), Linuxkit
binaries are somewhat out of date.

Note that containerd and hcsshim for HCS v2 APIs do not yet support all the required
functionality needed for docker. This will come in time - this is a baby (although large)
step to migrating Docker on Windows to containerd.

Note that the HCS v2 APIs are only called on RS5+ builds. RS1..RS4 will still use
HCS v1 APIs as the v2 APIs were not fully developed enough on these builds to be usable.
This abstraction is done in HCSShim. (Referring specifically to runtime)

Note the LCOW graphdriver still uses HCS v1 APIs regardless.

Note also that this does not migrate docker to use containerd snapshotters
rather than graphdrivers. This needs to be done in conjunction with Linux also
doing the same switch.

Brian Goff 86ba63db82 Ensure CPU quota/period updates are sent to runc
Fixes an issue where if cpu quota/period is sent via the update API, the
values are updated in the stored container data but not actually sent to
the running container.

Yong Tang 6102243692 Add `--cpus` support for `docker update`
This fix tries to address the issue raised in 31032 where it was
not possible to specify `--cpus` for `docker update`.

This fix adds `--cpus` support for `docker update`. In case both
`--cpus` and `--cpu-period/--cpu-quota` have been specified,
an error will be returned.

Related docs has been updated.

Integration tests have been added.

This fix fixes 31032.

This fix is related to 27921, 27958.
