Drop domain from supersede-hostname in dhcp conf

In the configuration file for dhclient, make sure to set the hostname without
the domain name (which is specified in a separate setting).

Configure the DHCP client to prepend the configured domain name to the
search list in resolv.conf.

Drop generic/openshift.ks

After commit 445b9d2b585de568981b3a2ef89c99a43c839a4a, there is little
difference between the regular openshift.ks and generic/openshift.ks, so
drop the latter as well as the generic/converter script and Makefile rule
that generated it.

The only difference in generic/openshift.ks was that it had an
additional call to configure_console_msg, which adds some information to
/etc/issue.  Commit 74847cb06409e77d5ff865583f615da83898bd94 added this
call to openshift.ks, and so generic/openshift.ks ended up with two
calls to configure_console_msg.  By deleting generic/openshift.ks, this
commit resolves that issue.

This commit also comments out the call to configure_console_msg when
generating openshift-amz.sh.
Only add the host property to jetty.xml if it doesn't already exist

Previously, if you ran openshift.sh multiple times,
/etc/activemq/jetty.xml would end up with multiple copies of the host
property line, which caused ActiveMQ to fail to start up.
Don't display grep results when searching for host property in jetty.xml
