ALF-9611 RSOLR 049: Share works against SOLR

- mostly working with bugs raised or the issues found
- ALF-9627 	RSOLR 049: Support for TAG list - simple field facettting
  - was not required. Facetting alpha is there (limits not set and need to go into JSON) - added to result set
- ALF-9628 	RSOLR 049: HTTPClient pooling and sharing by query
  - pooled for query, one reused instance for each tracker (could be shared)
- ALF-9629 	RSOLR 049: Support for PARENT field and start of PATH rebuilding other index tracking (group and site search)
  - done - also started PATH change and returns other data as not yet finished (QNAME is the most obvious)
  - fixed up and tidied query generation for index tokenisation mode form the model and what the query would like
