The `_index` field is now a completely virtual field thanks to elastic#12027. It is no longer necessary to index the actual value of the index name. closes elastic#12329

This change allows queries to test the name of the index by referring to the _index field in query clauses. Adding this capability means we can deprecate the specialist indices query.
IndexFieldMapper is changed to make the term(s) query factory methods instead produce match_all or match_none queries based on tests of the index name.
Closes #3316
