Detailed bug description:
When trying to build ISOs for fuel <= 8 where we build docker images, the process fails on trusty due to the older docker untilities (1.5.0) being used which can no longer pull down images from the docker hub.

Steps to reproduce:
1) git clone fuel-main
2) git checkout stable/8.0
3) run prepare-build-env.sh
4) make iso

Expected results:
built iso

Actual results:
failure:
sudo docker build -t fuel/fuel-centos-build /home/fuel/git/fuel-main/build/docker/fuel-centos-build
Sending build context to Docker daemon 15.87 kB

Reproducibility:
100%

Workaround:
Pull in upstream docker package, see https://git.opnfv.org/cgit/fuel/tree/build/Makefile#n115
