docs: Indicate that we have sent a request message to this neighbour.
  
  This will mean that a timer is created for 5 seconds waiting
  for a response.  If no response is received, then the timer will pop
  and log a console message to indicate that the pubsub topology will
  not be consistent.
  
  To remove the Timer, this neighbour must receive either a RESET, REPLY
  or a REQUEST SubscriptionMessageType.
