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 git-svn-id: https://svn.alfresco.com/repos/alfresco-enterprise/alfresco/HEAD/root@29585 c4b6b30b-aa2e-2d43-bbcb-ca4b014f7261
