This change implements the same preview behavior we have for cloud stacks, in pkg/backend/httpbe, for local stacks, in pkg/backend/filebe. This mostly required just refactoring bits and pieces so that we can share more of the code, although it does still entail quite a bit of redundancy. In particular, the apply functions for both backends are now so close to being unified, but still require enough custom logic that it warrants keeping them separate (for now...)
