The current API allows listings of the neturon server version without authentication. Because pecan was treating this like a normal controller, it was requiring keystone authentication. This adjusts the version listing to behave as a wrapper so it can be placed outside of the keystone authentication wrapper to allow anonymous queries. Closes-Bug: #1556038 Change-Id: I9f5aa3bea0e11c5e179fc286f9fa350b3930364f
