[CentOS-mirror] New Mirror

Hello. I'd like to submit my new mirror to the directory.
http://centos.someimage.com/ sponsored by "SomeImage Image Hosting" at 
http://someimage.com located in Colorado, USA
The bandwidth available is 10gbps, though the maximum throughput is 
around 150MB/s due to HDD transfer limitations. Basically it's fast.

Thanks,
- Mike
