Use local RHEL repositories with RHEL 7.4

This will remove the majority of our network traffic from the outbound
connection while provisioning. Also proxy was removed for
yum, as there is no point in proxying local data.

As a side effect, this makes provisioning currently faster by
reducing the time it takes by 35%.
