  MID-9106: Reuse WebClient per node and limit to 1 concurrent message

  - Introduced simple caching of WebClients - one client per seen node
    (see reasons below)
  - Use of WebClient needs to be synchronized - class is stateful
    this limits current cluster calls to one outstanding per node
    (may be problematic with larger transfers, maybe client pooling
     would help, )

This fixes crash and restart of a cluster node but may have negative performance impact.
