Add system fields to input sources. (#15276)
* Add system fields to input sources.

Main changes:

1) The SystemField enum defines system fields "__file_uri", "__file_path",
   and "__file_bucket". They are associated with each input entity.

2) The SystemFieldInputSource interface can be added to any InputSource
   to make it system-field-capable. It sets up serialization of a list
   of configured "systemFields" in the JSON form of the input source, and
   provides a method getSystemFieldValue for computing the value of each
   system field. Cloud object, HDFS, HTTP, and Local now have this.

* Fix various LocalInputSource calls.

* Fix style stuff.

* Fixups.

* Fix tests and coverage.
