installer: de-deplux activemq network connectors

Bug 1070747 - de-duplicate connectors on Network of ActiveMQ Brokers
https://bugzilla.redhat.com/show_bug.cgi?id=1070747

From docs bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1066729
Procedure 7.20. To Configure a Network of ActiveMQ Brokers
Links to a broker configuration which uses duplex
NetworkConnectors. These duplex network connectors need only be
configured from the initiating broker, not on both sides of the
connection.
installer: fix connector names

Really trivial, just trying to reduce confusion; the connector for
queues was named "-topics" and vice versa.

openshift.ks: Delete sed command for openshift.sh

openshift.ks: Delete the sed command that generates openshift.sh because
this sed command is no longer adequate (it is missing some step that the
Makefile performs to generate openshift.sh, and consequently it generates
a script that does not work properly).

README.md: Add a paragraph to explain the relationship between openshift.ks
and openshift.sh.

This commit fixes bug 1079939.
