Bug details

Describe the bug

When using the template vhost proxy.tmpl, the generate apache configuration does not include any DocumentRoot.

Even if DocumentRoot is explicitly specified in the pilar config, the template ignores the directive.

Steps to reproduce the bug

No special actions required to reproduce, just configuring a simple vhost.

Expected behaviour

The generated "sites-available/00-default.conf" file should contain a DocumentRoot directive.

Attempts to fix the bug

As a workaround, I'm adding the DocumentRoot with Formula_Append.
