This commit upgrades github.com/containerd/typeurl to use typeurl.Any.
The interface hides gogo/protobuf/types.Any from containerd's Go client.

when user executes ctr run --cni to start a container,it will call cni plugin to create network .But when user kills it,the network won’t be removed. if we run a container with same namespace and name again will trigger a bug. we should remove the network when user kills task if it enables cni plugin.

This change ignore errors during container runtime due to large
image labels and instead outputs warning. This is necessary as certain
image building tools like buildpacks may have large labels in the images
which need not be passed to the container.

It seems like the cwd flag isn't used anywhere for ctr tasks exec. This change

Go 1.15.7 contained a security fix for CVE-2021-3115, which allowed arbitrary
code to be executed at build time when using cgo on Windows. This issue also
affects Unix users who have “.” listed explicitly in their PATH and are running
“go get” outside of a module or with module mode disabled.
This issue is not limited to the go command itself, and can also affect binaries
that use `os.Command`, `os.LookPath`, etc.
From the related blogpost (ttps://blog.golang.org/path-security):
> Are your own programs affected?
>
> If you use exec.LookPath or exec.Command in your own programs, you only need to
> be concerned if you (or your users) run your program in a directory with untrusted
> contents. If so, then a subprocess could be started using an executable from dot
> instead of from a system directory. (Again, using an executable from dot happens
> always on Windows and only with uncommon PATH settings on Unix.)
>
> If you are concerned, then we’ve published the more restricted variant of os/exec
> as golang.org/x/sys/execabs. You can use it in your program by simply replacing
This patch replaces all uses of `os/exec` with `golang.org/x/sys/execabs`. While
some uses of `os/exec` should not be problematic (e.g. part of tests), it is
probably good to be consistent, in case code gets moved around.

systemd uses SIGRTMIN+n signals, but containerd didn't support the signals
since Go's sys/unix doesn't support them.
This change introduces SIGRTMIN+n handling by utilizing moby/sys/signal.

add '--snapshotter-labels' in ctr run and ctr c create
which can pass labels to snappshotter on preparing new
snapshot.
Pass command label to snapshotter can help it determine
which kind of writable snapshots should be provide.
For some snapshotter, such as overlaybd:
( https://github.com/alibaba/accelerated-container-image ),
it can provide 2 kind of writable snapshot (overlayfs dir or
blockdevice) by command label values.

This enables cases where devices exist in a subdirectory of /dev,
particularly where those device names are not portable across machines,
which makes it problematic to specify from a runtime such as cri.
Added this to `ctr` as well so I could test that the code at least
works.

Go example:
```go
opts := []converter.Opt{
// convert Docker media types to OCI ones
converter.WithDocker2OCI(true),
// convert tar.gz layers to uncompressed tar layers
converter.WithLayerConvertFunc(uncompress.LayerConvertFunc),
}
srcRef := "example.com/foo:orig"
dstRef := "example.com/foo:converted"
dstImg, err = converter.Convert(ctx, client, dstRef, srcRef, opts...)
fmt.Println(dstImg.Target)
```
ctr example: `ctr images convert --oci --uncompress example.com/foo:orig example.com/foo:converted`
Go test: `go test -exec sudo -test.root -test.run TestConvert`
The implementation is from https://github.com/containerd/stargz-snapshotter/pull/224,
but eStargz-specific functions are not included in this PR.
eStargz converter can be specified by importing `estargz` package and using `WithLayerConvertFunc(estargz.LayerConvertFunc)` option.
This converter interface will be potentially useful for converting zstd and ocicrypt layers as well.

Starting with go1.14, the go runtime hijacks SIGURG but with no way to
not send to other signal handlers.
In practice, we get this signal frequently.
I found this while testing out go1.15 with ctr and multiple execs with
only `echo hello`. When the process exits quickly, if the previous
commit is not applied, you end up with an error message that it couldn't
forward SIGURG to the container (due to the process being gone).
