Update Apache recipe for Omnibus

[fmestrone]

The suggested configuration here does not work for the Omnibus installation as some of the folders have changed. This file works for me on Ubuntu 14.04 LTS with Omnibus 1.1 for Gitlab 7.9.1 - when this works, the nginx web server is not needed anymore and can be disabled in gitlab.rb, as well as setting the url to https://git.example.com, like so

external_url 'https://git.moodsdesign.com' nginx['enable'] = false

How does this handle the new /uploads location in nginx?

Also @sajattack proposed a similar PR in #256 but I don't feel confident in replacing apache's init service.

i believe we can somehow combine your efforts guys.
