Need to create some documentation for "remote Puppet CA" configuration

We have some puppet server documentation which covers the use case of configuring Puppet Server for an "external CA" scenario - http://docs.puppetlabs.com/puppetserver/1.0/external_ca_configuration.html.

There are a number of users, however, who are looking to configure a Puppet Server master for environments where the "external CA" is actually a Puppet CA - e.g., where each Puppet Server master can be one of a group of masters all configured to use a remote Puppet CA, the latter of which may happen to be a Puppet Server instance as well. The existing "external CA documentation", however, is not well-suited for walking a user through how to enable this use case. A number of IRC users have encountered issues with the "remote Puppet CA" configuration - e.g., getting the master into a state where it has the "wrong" set of certificates configured. We should supplement the existing documentation with some documentation more oriented toward "remote Puppet CA" use cases.
