Use centos hosted mirror to sync CentOS content

Instead of using external public mirrors, the CentOS team is allowing
openinfra to sync to the core repo mirrors which should provide a more
reliable source for the repos [1].

In case of issues with the repos, the official way to contact CentOS
team is via a ticket to the centos-infra tracker [2].
