Adds a new module `modules` with two helper functions for module extensions: * `use_all_repos` makes it easy to return an appropriate `extension_metadata` from a module extension (if supported) to indicate that all repositories generated by the extension should be imported via `use_repo`. * `as_extension` turns a WORKSPACE macro into a module extension that uses `use_all_repos` to automate the generation of `use_repo` calls.
