pecan doesn't allow unauthenticated version request

[Kevin Benton]

The pecan version listing doesn't allow unauthenticated requests to '/' for version listings like the current wsgi framework. This prevents devstack from detecting that Neutron has started.

    Pecan: Allow unauthenticated version listing

    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.
