In interconnect guide, there seems to be no mention of the "http: yes" setting for listeners, see test test_websockets_option_for_listeners in https://gitlab.mw.lab.eng.bos.redhat.com/msgqe/dtests/blob/master/dtests/tests/InterconnectManualTests.py#L2038

In console guide there are steps about websockify which should not be there, per https://issues.jboss.org/browse/ENTMQIC-1886. Instead, user should be told to just set http: yes on a listener.
