strict JSON parsing with Jackson

Issue Description:
 
Integration tests in drools-ansible-rulebook-integration sometimes use non-compliant JSON.

Consequently jackson is allowing for non-standard JSON (eg: unquoted key in json object, quoting with ' instead of ")

 
Acceptance Criteria:
 
Rewrite integration tests to use standard JSON always.

Remove Jackson configuration for non-standard JSON, and use default JSON processing.
