blueprint for 2.1.2 deployment-handler

blueprint for 2.1.2 deployment-handler

- external version 2.1.2, internal version 4.4.2
- fixed 500 "value" argument is out of bounds
- convert the EOL to linux "\n" in the blueprint
   before zipping and sending to cloudify to avoid crashing
   when the blueprint is windows "\r\n" or mac "\r" based
- on catching the exception - log the stack
- added logger.info that replaced the logger.debug
   in a variety of places
