Have the `branches` API work with the new protected branches data model.

1. The new data model moves from `developers_can_{push,merge}` to
   `allowed_to_{push,merge}`.

2. The API interface has not been changed. It still accepts
   `developers_can_push` and `developers_can_merge` as options. These
   attributes are inferred from the new data model.

3. Modify the protected branch create/update services to translate from
   the API interface to our current data model.
