Cleanup tasks
=========================================
-* [armband-rpm-repo] Armband CentOS repository as additional repo (x86_64)
* [arm64-master] Find `puppetlabs-products` repo for arm64.
* [arm64-master] Fix license in ubuntu_1404_arm64.pp
* [arm64-master] Look into default ubuntu_debootstrap change in cobbler.pp
* [ohai] ThunderX network card speed reported as N/A
* [arm64-master] change docker repo in `upstream/fuel/build/config.mk`,
perhaps by figuring out current architecture with `uname -m`
-* [arm64-master] Fuel Master YUM repos still point to mirror.fuel-infra.org,
- due to bootstrap_admin_node.sh hardcodes from OPNFV
Needed for all arch support (todo, later)
