Moved EventExpander and EventUtil classes that require JDBC into Eventd to remove dependency
on database in the opennms-config-model and opennms-config packages. Moved the old Capsd
model objects (Db*Entry) back into Capsd to remove opennms-model dependencies on the database.
Added an opennms-config-api JAR to contain interfaces for opennms-config implementations.
Updated Spring dependencies to use the Spring EBR versions of the main Spring JARs so that
they have Karaf-compatible OSGi metadata. Added more Spring exclusions to the ActiveMQ
dependency list.
