Fix Besu integration test (#1174)

* Change opened RPC WS API names to upper case, lower case names resulted in error.
* Remove the custom docker build from the network, use the Besu image directly and set the required parameters on the container.
* Fix the Besu version to 21.10.1
* Add some docker container log dumps in case of CI test failure
