Section Number and Name: 
2.2.127. create a RoleBinding

Describe the issue: 
Documentation says you should use POST to create a rolebinding however in testing with the customer, we determined you need PUT instead

Suggestions for improvement: 
Verify if the documentation is correct and we should be using POST (I will log a bug on that if necessary) or if PUT was the intended command, and the documentation needs to be corrected.

Additional Information:
This was specifically done using `curl` and it even had to have -XPUT, not POST or just PUT.
