Subject: [PATCH] ISLANDORA-1522 global UUID setting enforcement

Addresses https://jira.duraspace.org/browse/ISLANDORA-1522

Added local methods(override) to handle global UUID settings. Changed
default valued for $create_uuid to NULL to allow developers to override
the global setting if needed.

This pull is part of a series of other pulls to make this change apply
to other modules
