import-verifier: use yaml for inline comments
For iterative cutting of dependencies, we will have temporary execeptions
in hack/import-restrictions.json. In order to document that, comments would
help a lot and using yaml is simple and gives us that.
In order to check if an import is of an allowed tree, we need to check
that the import is either literally to the base of the tree or that the
import is below the tree (the import, suffixed with `/`, should be a
prefix) instead of checking simply that the import is a prefix of the
allowed tree, as that causes issues with packages that are prefixes of
each other, like `k8s.io/api` and `k8s.io/apimachinery`.
