    Fix create mongodb cluster error in multi-network env

    Currently, the code pass "nics=None" when create mongos and config-server
    during creating mongodb cluster. If we didn't specify the parameter
    `default_neutron_networks` in trove config file, the value "None"
    will pass in nova.server.create() eventually, and in a multi network
    openstack environments, this could raise a “Multiple possible networks
    found, use a Network ID to be more specific" conflict.
    This patch fix the bug by specify the value of nics, besides, since the
    method `validate_instance_nics` has been added[1], we can safely use the
    first value of instances just like "volume_size".
