docs: Purge a connection from this group from within invalidate processing.
  Purging a connection removes it from the group even if the connection
  still has conversations associated with it.
  The purged connection is closed and not added to the idle pool.
  
  @param connection The connection to purge
  @param notifyPeer Should we notify our peer that the connection is being closed?
