Make some network parameters configurable
- maxtotalconnections = maximum number of total full connections
  (incoming + outgoing) the node will allow. Default 200 as it was.
- maxbootstrapconnections = number of additional (to total) connection
  that will act in bootstrap mode, closing after sending the list of
  addresses. Default 20 as it was.
- maxaddrperstreamsend = initial address list maximum size, per
  participating stream. Default 500. Child streams get half. The
  response is chunked into pieces of max. 1000 addresses as that's the
  protocol limit.
