Metacat

Disable indexing of 'prov_hasSources' field

Fix problem with prov_hasSources not being indexed

Add check in iindex unit test for 'prov_hasDerivations' field

Merge the code for rdfxml subprocessor from d1_cn_index_processor to metacat.

Add the prefix "prov_" the solr fields.

Use a new class to overwrite the class RdfXmlSubprocessor in d1-processor since that one has a method to use solr http server directly.

use input stream instead of Document for resource map processing test

update to use v2 types for indexing

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

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.
