    Check proxy env vars

    If a user is using http_proxy or https_proxy but is not excluding
    localhost from being proxied via the no_proxy var it can lead to a
    failure when we try and talk to the heat api. This change adds a check
    that is used for both the standalone tripleo deploy command and
    the undercloud install to ensure the end user does not hit this
    condition.
