pkg/oci is a general utility package with dependency chains that are
uneccessary for the shim.
The shim only actually used it for a convenience function for reading
an oci spec file.
Instead of pulling in those deps just re-implement that internally in
the shim command.

This adds trace context propagation over the grpc/ttrpc calls to a shim.
It also adds the otlp plugin to the runc shim so that it will send
traces to the configured tracer (which is inherited from containerd's
config).
It doesn't look like this is adding any real overhead to the runc shim's
memory usage, however it does add 2MB to the binary size.
As such this is gated by a build tag `shim_tracing`

Allow the api to stay at the same v1 go package name and keep using a
1.x version number. This indicates the API is still at 1.x and allows
sharing proto types with containerd 1.6 and 1.7 releases.

The new `PlunginInfo()` call can be used for instrospecting the details
of the runtime plugin.
```console
$ ctr plugins inspect-runtime --runtime=io.containerd.runc.v2 --runc-binary=runc
{
"Name": "io.containerd.runc.v2",
"Version": {
"Version": "v2.0.0-beta.0-XX-gXXXXXXXXX.m",
"Revision": "v2.0.0-beta.0-XX-gXXXXXXXXX.m"
},
"Options": {
"binary_name": "runc"
},
"Features": {
"ociVersionMin": "1.0.0",
"ociVersionMax": "1.1.0-rc.2",
...,
},
"Annotations": null
}
```
The shim binary has to support `-info` flag, see `runtime/v2/README.md`
