Do not use reflection for injecting the DslQueryProcessors
- trade terseness for easier understanding of the code and maintainability - Split up DslQueryProcessor in two separate classes (v1 and v2) Issue-ID: AAI-3786 Change-Id: I7fe0411f6b694eb82616ac4a61a5376c630b5b2a Signed-off-by: Fiete Ostkamp <Fiete.Ostkamp@telekom.de>
