Metacat

Add the code to handle the merge-needed fields having multiple pairs.

During index merging process, if a field is a system metadata field and current document doesn't have the field, we don't need to merge it from the existing solr document.

re-include mdq context file after merge

include mdq composite score

remove root node in xpath (for some reason this wasn't working on mn-demo-8 but was locally).

Increase the version to 2.8.1

Merge the code for rdfxml subprocessor from d1_cn_index_processor to metacat.

include v1 in the run mdq formatId

Add the prefix "prov_" the solr fields.

adjust color-based score calculations to match UI and add up to total result count
