Metacat

Use the Collections class from java.util.

-generate system meta for all docids, even those not originating on the server (replicas from the past)
-generate ORE docs and download remote data only for those documents that originated on this server being upgraded.

refactor generate system meta loop to the factory class -- to be reused in sysmeta and ORE generation

do NOT generate ORE maps or download data when we do the initial System Metadata generation -- this is deferred until D1 registration.

make more generic so that a custom list of IDs can be passed in.

insert OR update system metadata -- no need to do an update right after initial insert...

call the System Metadata generator during upgrade to 2.0.0

In IdentifierManager.updateSystemMetadata(), add a check for invalid system metadata (fields that throw a NullPointerException on access) to ensure that system metadata is populated correctly. Updated calling classes to handle the exception.

store D1 configuration properties in the main backup so that they persist between upgrades.

update authoritative member node id when we change it (reconfiguration) and when we initially register as a MN with the CN.
