Description

basically, configurations defined via annotation classes can be used for both single or collection configuration access. but in most cases it's only used for one or the other.

we should add a "collection" property in the @Configuration annotation so annotation classes can be marked for their primary usage, and make this information accessible via the SPI and ConfigurationManager APIs.
