    Fix Aodh's health checks

    HAProxy currently checks aodh backend with "HEAD /" and an expected
    return code of 401. The request actually returns "200 OK". The 401 would
    be returned if the check would target "HEAD /v2", but as all other
    backends that do not implement "/healthcheck" also check "HEAD /" for
    2xx/3xx return codes, I removed the wrongly expected "401".
