Metacat

Add a test method to test the method determining if there is a delete event for the given id.

In InsertORETest: Set the format ID of the metadata object to an EML formatId so that it gets indexed correctly.

Add a test class that inserts an ORE with PROV relationships

use mock CN for testing metacat implementations

remove unused tests

add support for v2 DataONE API.

handle login/logout when testing using metacat client (recent refactoring to use more standard http client code)

remove dependency on HttpMessage that was in the utilities project but is now removed in favor of newer (standard) http client library code.

take advantage of the ezidclient for multi-threaded/asynchronous DOI registration. This will be most useful for doing large batch updates and not so much for the one-at-a-time publish actions but works in either context. https://projects.ecoinformatics.org/ecoinfo/issues/6440

use separate surName and givenNames to lookup ORCIDs.
