Subject: [PATCH] LP#1673857: add open-ils.circ.copy_tags.retrieve[.staff]

These are methods to retrieve the set of copy tags associated
with a copy, scoped to an OU and its descendents at a
optional depth. The .staff version includes both
public and non-public notes (and requires STAFF_LOGIN
permission).
