Manage Apache LogFormat with foreman-installer

Hi all,

I am looking for a way to get response times in the access logging of my
apache vhost. Right now I have the following configuration in my
25-puppet-http.conf vhost file (which is managed by foreman-installer
version 1.14.3)?

Logging

> ErrorLog "/var/log/apache2/puppet-http_error.log"
> ServerSignature Off
> CustomLog "/var/log/apache2/puppet-http_access.log" combined

The combined LogFormat is the default one of apache2, specified in
/etc/apache2/apache2.conf:

LogFormat "%h %l %u %t "%r" %>s %b "%{Referer}i" "%{User-Agent}i""
> combined

I've been looking in the puppetlabs/puppetlabs-apache2 and
theforeman/puppet-puppet repository but I can't seem a way to manipulate
the LogFormat.

Is it possible to manipulate LogFormat, be it in the apache2.conf or
25-puppet-http.conf file?

Thank you,
Joost
