    Check for AODH host before adding alarm_connection

    Currently the os_ceilometer role will configure ceilometer.conf to
    include a line in the [databases] section for alarm_connection no matter
    what, and it will default to looking for the aodh user in mongodb
    serving at localhost. If the user installs ceilometer but not aodh, this
    will break the ceilometer service as the API will not start up while it
    times out looking for the unconfigured database. This patch ensures that
    there are hosts configured for AODH before adding that line to the conf
    file.
