docs: // TailingLogs listens indefinitely for log messages only; other event types
  // are dropped.
  // Whenever an error is encountered, the error will be sent down the error
  // channel and TailingLogs will attempt to reconnect up to 5 times.  After
  // five failed reconnection attempts, TailingLogs will give up and close the
  // error and LogMessage channels.
  //
  // If c is closed, the returned channels will both be closed.
  //
  // Errors must be drained from the returned error channel for it to continue
  // retrying; if they are not drained, the connection attempts will hang.
