Generate field anchors

[jsoref]

For cert-manager, there is a page with: https://cert-manager.io/docs/reference/api-docs/#cert-manager.io/v1.CertificateSpec

We'd like to be able to link to: renewBefore, it could be of the form https://cert-manager.io/docs/reference/api-docs/#cert-manager.io/v1.CertificateSpec/renewBefore.

I think I'd want the field names to be self links so that people could easily share links to specific items (this should really apply to resource types as well).
