2.11.0
Restore accidentally dropped ability for ModuleStream.read_*() functions to transparently read packager-v3 documents, deprecate them in favor of the new Modulemd.read_packager_*() functions, and add notes to their documentation about the limitations of the packager-v3 to stream-v2 conversion.
Implement public APIs Modulemd.read_packager_file() and Modulemd.read_packager_string()
