Create a helloworld helm operator example

Describe the solution you'd like.

Create a super simple helloworld helm operator example. Ideally it will be a similar development process as the ansible operator example. This could be a good chance to ensure the Open Horizon agent is able to work with operators created with newer versions of operator SDK.
