In https://github.com/containerd/containerd/pull/7764 it was made
so that generic runtime options in the containerd toml config file
would get passed to shims regardless of if containerd knew of the
type beforehand and could supply the struct. However, this was only
added for the sandbox server fork here and not the regular ol' CRI
server. This change just mirrors the parts that need to be plopped in
pkg/cri/server
