Configuration for deploying automatically from Travis-CI

Details
-------
Credentials need to be updated. This is not working right now.

I'm adding two alternative ways since I can not test fully.

1) Using maven cloudfoundry plugin. Might be incompatible with cloudfoundry V2 API
2) Using a helper script (deploy_to_cloudfoundry.sh). This is more flexible and
uses cf V2 command line tool
