In some cases, when a cert is about to expire, we get an alert about it from every single proxy, which is excessive. This notably happens with the checks in nagios_server/files/nagios/services/ssl.cfg which have hostgroup_name proxies.
nagios_server/files/nagios/services/ssl.cfg
hostgroup_name proxies
These should all just be listed under one server, not all the proxies for our sanities.
This is a relatively simple change and would make a good easyfix for someone looking to make one of their first patches.

This is easy enough to change, but... one reason we wanted all the proxies checked was in case we rolled out a new cert and somehow some subset of them didn't update and still had the old cert.
ie, we could just check one, but then we might miss if there's others that are effected.
Not sure whats best here...
@codeblock you still want to try and do this some different way?
I wonder if we could make them all depend on each other as far as nagios knows and the other ones would all be deps of the first one in the case where they are all bad, but only one would alert in the case of one bad?
I'll take a look, lets see what I can come up with @lgriffin
I wonder if this will work. It checks the certs on koji.fp.o and proxy03.fp.o and suppresses warnings of the koji and proxies hostgroups when this check already returns WARN or CRIT. pagure as a single host can send out notifications whenever necessary. caveat: we won't get notifications about ssl certs from koji and proxies hostgroups until the certs on koji.fp.o and proxie03.fp.o get fixed.
