first attempt at a crate

[upgrad...@gmail.com]

Hi all, here's my first attempt at writing a crate: 

https://github.com/upgradingdave/httpd-crate

I didn't see any crates written yet for apache so decided to take a stab at it. 

As mentioned in the README, it's pretty basic and only does the bare minimum of what I need at the moment which is to install apache2 on Ubuntu and then set up a virtual host to proxy requests to a java process. 

So it won't work on any other OS's than Ubuntu at the moment, and it's probably very naive code (as I'm still learning how pallet works), but it gets the job done for me! Just wanted to let folks know it's out there in case it's useful to anyone else.
