    Sets the time interval between regular application-level ping messages that
    are sent to ensure that transport connections to nodes belonging to remote
    clusters are kept alive. If set to `-1`, application-level ping messages to
    this remote cluster are not sent. If unset, application-level ping messages
    are sent according to the global `transport.ping_schedule` setting, which
    defaults to `-1` meaning that pings are not sent.
