Create remaining spring docs

Presuming that the embedded, dev, and security docs will all be available as part of their respective code (javadocs and examples), that leaves admin, caching, and client-dev as the remaining books that need a spring specific spin.

Most of the admin guide is not applicable - but we do need to capture somewhere all of the information related to system/env properties

Most of the caching guide is TBD - but the sections on result set and other caching are still applicable.

Most of the client guide is applicable to spring.
