Fixes #12720 - Add tabs for puppet on proxy show page

This patch adds two tabs to the proxy show page related to puppet
1. Puppet - this tab is for proxies managing a puppet master. This tab
displays information about the puppet master, such as number of classes
in each environment, latest reports and so on.
2. Puppet CA - This tab incorporates the two seperate pages that were
already present for managing the puppet ca's certificates and autosign
entry. It also incorporated the new autosign form in a modal view.

Refs #12720 - Allow puppet CA cache to work for https proxies

When dumping CA certificates to cache, the status object is also dumped.
Since the status object points to the API resource, Marshal will try
dumping the API resource as well. This will fail for https proxies as
the SSL certificates cannot be dumped. This prevents the dumping of the
api link which will be recreated once the object is loaded back from
cache.
