Add rest api for Verification

/dmn/verification
-> for all verifications
/dmn/verification/type
-> list types
/dmn/verification/type/{typeName}
-> only verification for typeName
/dmn/verification/classification
-> list all classifications
/dmn/verification/classification/{classificationName}
- > all verifications for named classification
