[CentOS-mirror] GARR Mirror update

Dear CentOS mirror maintainers,

I'm a maintainer of the GARR Mirror system.
I'm contacting you because we are planning a new layout to improve 
performance and availability of our mirror system.

The new url for the CentOS repo is http://centos.mirror.garr.it/centos, 
please update all lists, the old name will be working as legacy system.
If any other names are required please inform us.

The new system will provide only HTTP access and, only if required, HTTPS.
We are also planning to setup a pool of reverse-proxy, behind 
round-robin DNS, with IPv4 and IPv6.

Afterwards, we would like to use pull-rsync method to keep the mirror in 
sync.
If official documentation is available, I would kindly ask you to send 
me a link.

Thank you in advance for your cooperation.

Best regards,
Paolo Velati
