Use /etc/puppet for client SSL certificates

[stbenjam]

Trying a puppet 3 install, and I get this error:

[ERROR 2016-08-04 10:36:46 main]  Could not set 'present' on ensure: No such file or directory - /etc/puppet/ssl/client_cert.pem at 39:/usr/share/katello-installer-base/modules/certs/manifests/puppet.pp

Looks like I was wrong (#95 (comment)) about /etc/puppet/ssl existing, just reverting it to the original place we were storing these for puppet 3.

Any particular reason to store this in /etc/puppet rather than the default /var/lib/puppet/ssl? I don't mind either way.

I'd rather just leave them where it was, since the focus is getting p4 to work. These are the certs used for the foreman node.rb thingy and it's in /etc/puppet too.

ACK, this means it's no change compared to the previous version which is a good thing for admins :)
