* move hwm into the zmq constructor and reconstruct the socket instead of rebind. seems to work better than rebind (most connections cant bind so fast?)

* fix after merge

* added tests to reconnect zmq sockets when setting rx zmqport and rx zmqhwm, changed the tests scripts a bit to make the receiver starting tcp port configurable

* tests: slsreceiver also starting up  with 2000 as default tcp port, using latest cli args for receiver and multi receiver

* releasr notes
