Metacat

add support for v2 DataONE API.

handle multiple subprocessors (RDF and ORE) before the object gets indexed by making sure to merge the solr doc map before submitting to the index.

use default "metacat" context name for metacat-index testing.

include ORE formatId as handled by the RDF subprocessor and index prov:wasDerivedFrom field where it exists in the RDF model. https://projects.ecoinformatics.org/ecoinfo/issues/6548

use a non-public rightsHolder for both EML and Annotation test documents now that the RDF subprocessor checks each annotation to see that it came from a user that as write permission for the object being annotated.

test for update using the updated EML file, not the original. Also add the SM to the shared map so that the indexing process can consult SM.accessPolicy when indexing annotations that assert things about those test documents.

ignore the metacat/solr comparator tests - they are one-offs.

pass around the object file path rather than the data stream so that multiple subprocessors can index the same object and not consume the stream before it gets to the next one. In preparation for extending the assertions stored in OREs. https://projects.ecoinformatics.org/ecoinfo/issues/6548

only allow multiple values for multi-valued fields....

use newer httpclient library so that Jena's dependency is met - this goes all the way back to d1_common/libclient needing to pull in the newer library.
