Classify more exceptions as unser indicated errors

* mqtt hive mq throws a NativeIoException when the address is somehow
  invalid
* http throws UnexpectedConnectionClosureException when the server
  closes the connection. This happens most likely because of a
  too high max idle time for the conneciton pool
* http throws a StreamTcpException stating that the Connection was reset by peer.
  This is not a ditto fault and therefore should not be treated as failure
