    Remove Keystone dependency from neutron-server RA

    When we check the availability of Neutron API service, now we simply
    check the response code of "List API version" call instead of getting a
    token from Keystone, then checking a Neutron API endpoint using that
    token. This way we don't need a token anymore so the checking process
    will not depend on the availability on Keystone.
