LP#1384740 marc_stream_importer auth and cleanup

Add support for importing authority records to marc_stream_importer and
clean up some cruft along the way.  A single instance of the script can
import either type of record.  The record leader is inspected to
determine if it's an authority record or not.

New options:

--auth-merge-profile
--auth-queue
--auth-source

Changed options:

--import-no-match
--auto-overlay-exact
--auto-overlay-1match
--auto-overlay-best-match

These have been expanded to include authority records.  No value or a
value of '1' means the option applies to bib imports, a value of 2
applies to authority records, and a value of 3 applies to both.

Cleanup:

--import-by-queue is no longer supported.  This option serves no
particular purpose and is a bad idea when re-using the same queue over
and over as most people do, because queue bloat will increase run times.

--noqueue (AKA "direct import") is no longer supported.  All imports go
through Vandelay now.
