Metacat

use Java-based temp file creation instead of Date (ms) timestamp to ensure uniqueness of the file and avoid re-use by two concurrent threads.

use current datetime (at system metadata generation) as the date last modified

Don't check for populated obsoletes and obsoletedBy fields during CN.create(), only MN.create(). The CN should expect that the MN has populated this field because of existing revision information, and should trust the MN information. Addresses https://redmine.dataone.org/issues/2507.

Some minor logging changes.

use scope prefix (knb-lter-%) for random test doc population

use isAdminAuthorized() to check access to CN.create(). Note this method takes a pid and permission parameter and neither is used. Also removed the NotFound exception because it would never come up.

check that caller is CN/admin for CN.delete()
https://redmine.dataone.org/issues/2506

include CN.delete()

Notify each replica MN when critical portions of system metadata change so the MN can pull the latest copy into its store. AccessPolicy and RightsHolder changes are the most critical for the MN to keep updated on.

Only allow CNs to call MN.synchronizationFailed() by calling isAdminAuthorized(). The pid must also be valid.
