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`
