make nginx replaceable with a different httpd

[igalic]

Rationale: We know Apache httpd. We know how it behaves we know
how to debug, tune, etc.. it. We don't know nginx.

We'd like to be able to replace it.

I'll look into providing patches.

In 2013, people don't know perfectly about nginx ? no, realy ? :-)
sorry, joke aside, it would be nice indeed!

I'm an Apache committer, so it's tribal thing ;)

This goes back to our dependencies again and where we choose to draw our lines. Obviously, Apache support would be great. Does it mean we add logic to install Apache or nginx with this GitLab module? Or do we pull nginx out of this module, install it in gitlab_requirements and allow others to install whatever httpd they want?

I have some random thoughts on this that I will post somewhere later tonight when I am off work.
