Eliminate duplicate code between ConfigurationClassApplicationContext and ConfigurationClassWebApplicationContext [SPR-6186]

[spring-projects-issues]

Chris Beams opened SPR-6186 and commented

Due to multiple inheritance issues, CCAC and CCWAC cannot share @Configuration class processing behavior through a common superclass. Factor out a static util (probably as an inner class of CCAC) and refererence it from CCWAC as necessary to eliminate duplicate code.

Introduced ConfigurationClassApplicationContext.Delegate to encapsulate behavior common to the two app context implementations.
