Imports for Spring dependencies have been removed from the dependencyManagement sections from the blueprint-parent POMs.

They were redundant with imports in the com.coremedia.cms:common-thirdparty-for-plugins-bom. Furthermore they overrode some exclusions from that BOM and thus accidentally lead to inconsistencies in the application class paths.

This change is considered breaking, because it removes the version properties spring-framework.version and spring-security.version from the parent POMs. In the default blueprint, they were configured with the same version that are defined in the com.coremedia.cms:common-thirdparty-for-plugins-bom anyway. But customers who want the customize these versions now have to introduce a dependencyManagement for these dependencies theirselves.
