Description:

def resource_op_defaults_to(name, op_default, value, extra_args=None, cibname=None):
    '''
    Ensure a resource operation default in the cluster is set to a given value

    Should be run on one cluster node only
    (there may be races)
    Can only be run on a node with a functional pacemaker/corosync

    name
        Irrelevant, not used (recommended: pcs_properties__resource_op_defaults_to_{{op_default}})
    op_default
        name of the operation default resource property
    value
        value of the operation default resource property
    extra_args
        additional options for the pcs command
    cibname
        use a cached CIB-file named like cibname instead of the live CIB

    Example:

    .. code-block:: yaml

        pcs_properties__resource_op_defaults_to_monitor-interval:
            pcs.resource_op_defaults_to:
                - op_default: monitor-interval
                - value: 60s
                - cibname: cib_for_cluster_settings
    '''
    return _item_present(name=name,
                         item='resource',
                         item_id='{0}={1}'.format(op_default, value),
                         item_type=None,
                         show=['op', 'defaults'],
