    Refresh local registry auth info each time when access local registry

    (cherry picked from commit 423a475aff4f9ea1b60af6a9a2989027d1506f10)

    Local registry uses admin account password as authentication info.
    And this password may be changed by openstack client at any time.
    When sysinv tries to download images from local registry, it cannot
    cache the auth info, otherwise it may lead to authentication failure
    in keystone, and account be locked at the end.
