[CentOS-mirror] Remove old mirror and add new one?

[Brian Rak]

We currently run the 'centos.mirror.choopa.net' mirror.  That machine is 
going to be replaced, and we'd like to move the mirror to a new 
hostname.  Also, the staff member listed as the contact there is no 
longer with the company.

The new machine is:

URL: http://centos.mirror.constant.com (IPv4 and IPv6)
Bandwidth: 1000mbps, unmetered
Location: Piscataway, NJ USA
Sync: every 5 hours

Mirror is run by 'Constant.com' www.constant.com
