    retry func iconfig_update_file when host personality is None

    when we run "system dns-modify" command, the command will response after
    sysinv-db was updated, and file "/etc/resolv.conf" will be updated
    asynchronously by another process "sysinv-agent". Once the attr
    "_ihost_personality" of agent is None(initial value), it will not update
    file "/etc/resolv.conf" and will not inform sysinv client also,
    which will lead command dns-modify failed silently.

    This patch will retry function iconfig_update_file by which sysinv-agent
    update file "/etc/resolv.conf" when attr "_ihost_personality" is None.
