Change request: make ping and traceroute tools work from Zabbix dashboard

[Jeffrey Ollie]

The ping and traceroute tools in the Zabbix dashboard do not work
because the web front end does not know how to connect to the Zabbix
server to initiate the commands.  The following patch adds that
configuration as well as tweaks a selinux boolean.  The Zabbix web
front end runs on the app servers so this is affected by the change
freeze.  The impact should be minor, reverting should be relatively
easy in case of problems.

"You know, I used to think it was awful that life was so unfair. Then
I thought, wouldn't it be much worse if life were fair, and all the
terrible things that happen to us come because we actually deserve
them? So, now I take great comfort in the general hostility and
unfairness of the universe."
