Open Stack

Hello

I have noticed that some openstack projects [1] use pylint gate job. 
 From my point of view it could simplify code reviews even as non-voing 
job and generally it could improve code quality. Some code issues like 
code duplication are not easy to discover during code review so 
automatic job would be helpful. Please let me know your opinion about 
that.  Thanks
