Move fetchers around to make them public

RequestsFetcher should still be public (even if deprecated).

* We don't want to import RequestsFetcher in __init__
  (because that requires importing requests)
* but we do want RequestsFetcher to be importable publicly

Move both fetchers out of _internal: that was never the right place for
them anyway: they are public modules.
