There was a cycle in the spring-boot-data-* modules.
SpringDataWebAutoConfiguration (which sits at the spring-data-commons
level) referenced RepositoryRestMvcAutoConfiguration (which sits
at the spring-data-rest level). This dependency's expressed in the
wrong direction as data-rest depends on data-commons. The resulting
cycle was not noticable as it was expressed through a String afterName
attribute on `@AutoConfiguration`.
spring-boot-data-commons was also using spring-boot-data-jpa for its
tests, which also results in an inverted dependency relationship.
This commit reworks things so that all of the spring-boot-data-*
modules depend upon spring-boot-data-commons, mirroring the
dependency relationship in Spring Data. The integration tests in
spring-boot-data-commons have been reworked to use Spring Data
directly, avoiding the need for a circular from
spring-boot-data-commons to another spring-boot-data-* module.
