upgraded to 3.5.

Issues encountered during upgrade. Data mapper issues (fixed my remapping division object and comparing with old output of the transformation), duplicate copy of contents from src/main/api to
src/main/app (did the clean up), automatic creation of lib folder with all libraries while importing the Mule archive to anypoint (removed the lib as it will be taken care of maven)
Merge branch 'feature/mule-upgrade-3.5.0' into develop
