Currently type references for non-local names are output as relative
types which is subject to the resolution rules as defined at
https://protobuf.com/docs/language-spec#reference-resolution
This works fine within the k8s.io namespace where no subpackages are
named k8s, but other users of go-to-protobuf likely have k8s in their
package name. This causes conflicts in the search resolution when
executing `go-to-protobuf`:
```
company.example.com/k8s/custom/pkg/apis/custom.k8s.example.com/v1/generated.proto:64:12: "k8s.io.apimachinery.pkg.apis.meta.v1.ListMeta" is resolved to "company.example.com.k8s.custom.pkg.apis.custom.k8s.io.apimachinery.pkg.apis.meta.v1.ListMeta", which is not defined. The innermost scope is searched first in name resolution. Consider using a leading '.'(i.e., ".k8s.io.apimachinery.pkg.apis.meta.v1.ListMeta") to start from the outermost scope.
```
To avoid this we can output fully qualified type references using a
preceding dot (.)
This results in a change for k8s generated.proto files, but the
effect is a noop.
