Ensure prefix is correct module prefix

- Moved Prefix logic from RI to Service layer
- Prefix is no PREFIX propety, not the moduel name!
== RI (DB Layer) Changes
- Removed prefix logic incl hazelcast
- Added new basic ri-test for getDataNode and assert prefix is null
- Updated exsiting ri-test to us getDataNode
- Updated existing ri-test to only use " where really needed
== CPS Service Layer Changes
- Introduced PrefixResolver with clear and limited responsibility
- Use PrefixResolver where needed
- Cache prefix map per anchor, use cached entry when available
- Disabled SONAR on new Regex
== REST Layer
- Use PrefixResolver where needed
