Document BeanFactoryPostProcessor implementation constraints [SPR-7466]

[spring-projects-issues]

Chris Beams opened SPR-7466 and commented

#12108, while not actually a bug in Spring per se, was ultimately related to a BeanFactoryPostProcessor implementation in Spring Security OAuth that was misbehaving by prematurely instantiating bean instances, ultimately subverting the normal bean post-processing lifecycle (specifically, AutowiredAnnotationBeanPostProcessor).

Document the constraints when implementing BFPPs, such that future authors don't make this mistake.

JavaDoc for BFPP, and relevant section(s) within the reference documentation should be updated.
