Support SpEL expressions in @Entry annotation

This is a spring-ldap companion of spring-data-ldap issue DATALDAP-23

The @entry annotation on the entity class requires 'base' and 'objectClasses' attributes. Unfortunately there's no easy way to avoid hardcoding values of these attributes. Please support SpEL for @entry attributes so that values can come from a standard property source.

any chance this feature can be added? Our directory has users under two bases (they don't share a parent). This feature is a MUST have in this case, if we also want to use the embedded ldap plugin (unboundid).

when will this functionality be added ?
