version 1.0.1 -> 1.1.0

replace {project.version} with hardcoded version in setup.py. Reason: This enables a user to simply clone the repository, and run setup.py to install (avoid the step of running 'mvn package' to simply insert the version there). In the future, we can have a script that updates this version and the version in clients written in javascript, ruby, etc in one step.
