need to use `hostvars[host]['XXX']` to retrieve the monitor
interface and/or radosgw interface.
Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=1493920
Signed-off-by: Guillaume Abrioux <gabrioux@redhat.com>
This patch adds passing the RGW_CIVETWEB_IP to the docker
container. This IP defaults to the value of radosgw_civetweb_bind_ip.
radosgw_civetweb_bind_ip default to ipv4.default
Without this value, the RGW containter will bind to 0.0.0.0
