Remove direct dependence on ced2ar-rdb

[bbarker]

There are a number of cases where ced2ar-rdb is a direct dependency of this project, and really it should not be the case. Instead, layers of indirection should be added, where appropriate, to ced2ar-core-services (or another services module).

• Remove dependencies by adding to services modules and refactoring.
• Remove dependency on cedar3-rdb in pom.xml
