Part 2 of ALF-9413 RSOLR 022: Fine-grained control of full-text indexing

Browse Source 
- big switch to turn off content indexing is working for lucene sub-system - catches up (eventually) via FTS as expected
- includes further improvements to subsystem shutdown which also relates to: ALF-9079 RSOLR 019: Lucene to SOLR switchover administration
- lucene indexes can be deleted after subsystem shutdown
- at subsystem  star the  index rebuilds if required and restarts FTS on load
- subsystem shutdown requires more work if two lucene subsytems are ever to exist together
   - does not shutdown existing IndexInfo work nicely -> possible exceptions as IndexInfo resources are cremoved and cleaned up from those expecting them to be there ... may regrab resourcse
