Added an LWRP to create kafka topic

Added a new resource/provider to create/modify Kafka topics.
I couldn't figure out a way to return true or false using a bash resource. As per my understanding the bash resource returns 0 if code is executed successfully and 1 if there is a failure. The resource fails itself and I do not know how to capture the value of the resource and based on that make a decision to return either true or false.
