> it adds ability to call Lucene's JoinUtil by specifying local param, ie  \{!join score=...}.... It supports:
> - {{score=none|avg|max|total}} local param (passed as ScoreMode to JoinUtil)
> - -supports {{b=100}} param to pass {{Query.setBoost()}}- postponed till SOLR-7814.
> - -{{multiVals=true|false}} is introduced- YAGNI, let me know otherwise.
