    Description

      We fixed MXS-4259
      but there is another case where substate involves 'leaving' that is still causing a similar warning in maxscale log.

      when a node is softfailed, it goes into leaving sub-state in xpand.

      2022-11-25 07:25:47   info   : [xpandmon] 'leaving' is an unknown sub-state for a Xpand node.
      

      if a late node is softfailed, it goes into 'late, leaving' sub-state

      We can safely ignore this sub-state as well and instead of Warning we should make it Info or simply not show it.
