Metacat

First pass at MN.getPackage() implementation using Bagit library from LOC. https://projects.ecoinformatics.org/ecoinfo/issues/6026

add method for publishing existing object (usually assumed to be scimeta) with a DOI. https://projects.ecoinformatics.org/ecoinfo/issues/6014

only use MapStore/MapLoader for saving/loading IndexEvent objects. No need to use a listener since there is only the single node -- all entries are persisted to DB using the hazelcast.xml config we have for the map. https://projects.ecoinformatics.org/ecoinfo/issues/5944

add MapStore/Loader test for the IndexEvents -- adding and removing events in the DB table through hazelcast. https://projects.ecoinformatics.org/ecoinfo/issues/5944

stub for storing IndexEvent objects in Metacat (from metacat-index processing). https://projects.ecoinformatics.org/ecoinfo/issues/5944

do not force a get() during refresh (causing EML-defined data access rules to be lost when inserting EML docs about data files). note that this reverses a change that was meant to trigger indexing, but now we are using a new queue to share index events with metacat-index and so should not be necessary.

correct regex for whitespace in D1 identifier.

use an independent ISet<SystemMetadata> structure to communicate objects that should be indexed by metacat-index. https://projects.ecoinformatics.org/ecoinfo/issues/5943

Solr will be enabled if it is in the db.enabledEngines.

Use some contants from the EnabledQueryEngines.
