Using puppetlabs/apache module

Here's a quick stab at converting to use puppetlabs/apache module. I did this prior to knowing about issue #78 

I know it worked against the 'master' branch on CentOS 6.x and i sync it against the v6.0.0 branch, leaving all the python virtualenv stuff intact.

I am getting an error though, so i cannot fully validate it. The error seems related to a missing graphite.db file, so syncdb is failing.
```
Error: /Stage[main]/Graphite::Config/Exec[Initial django db creation]: Failed to call refresh: echo $PATH; python manage.py syncdb --noinput returned 1 instead of one of [0]
Error: /Stage[main]/Graphite::Config/Exec[Initial django db creation]: echo $PATH; python manage.py syncdb --noinput returned 1 instead of one of [0]
```
Anyhow, i'd appreciate any feedback.
