<install> Write EOL to /etc/ssh/sshd_config

In the configure_sshd_on_node function in openshift.ks/openshift.sh, be
sure to write the \n EOL marker when adding the AcceptEnv setting.

After commit 24d469fd2f2aa0bcc0d430f7ee148598fdb29e23,
configure_sshd_on_node writes a \n to sshd_config _before_ the line that
the function adds, for the contingency that sshd_config already has an
incomplete line lacking the EOL marker.  However, after that commit, the
function wasn't writing the \n _of_ the line that the function adds.  This
commit makes the function write both \n EOL markers.

This commit fixes bug 1068649.

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.
