LP#1856868: Remove deprecated open-ils.circ.renew.auto API

The deprecated open-ils.circ.renew.auto API was removed.  You will
want to use open-ils.circ.renew with the auto_renewal option set
to 1.  This mainly affects those who have written custom code using
the open-ils.circ backend.

This removal was broadcast in the release notes for Launchpad bug
1835085: https://bugs.launchpad.net/bugs/1835085.
