DATACMNS-810 - Final tweaks to general Query by Example documentation.

Made the query-by-example.adoc a top level document. Clients including the documents have to tweak the indentation on the inclusion side then. Included query-by-example.adoc into index.adoc so that it can be double checked in test renderings easily.
