* **Project Board:** [AIP-85 Dag Importer (Project
#672)](https://github.com/orgs/apache/projects/672)
* 2nd PR for rewiring the Dag processing process with `sdk/importers`:
prepares the Task SDK importer registry so Dag processing can discover
definitions through importers instead of by file path.
---
Changes:
- `DagImporterRegistry.list_dag_definitions(bundle, safe_mode=...)` yields
each definition (or discovery error) in a bundle, paired with the importer that
listed it. The pairing is needed because a composite importer's members, such
as zip members, cannot be routed back to it by extension.
- `find_file_dag_definitions` accepts a single file as its root, so a parse
process can scope discovery to the file it was given.
- An importer whose extensions were all overridden, e.g. by a bundle's own
`ZipImporter`, no longer takes part in discovery. Previously it listed the same
zip members a second time.
- An importer config entry may be a bare classpath string, shorthand for
`{"classpath": "..."}`.
