Fuel master node on CentOS 7

Registered by Vladimir Kozhukalov on 2015-09-14

FUEL master nodes up to MOS 7.0 were built on CentOS6 base with many
packages rebuild internally even when there are suitable versions
available in upstream repositories. This becomes a problem since
codebase becomes outdated and there is a growing amount of security
patches that must be applied.

Updating master node to CentOS7 solves the following issues:

* Update system packages (including kernel) to newer versions

* Update core packages (docker, puppet, ruby, openstakc components)
  to newer versions

* Update a lot of other packages to newer versions

* Use upstream repositories with MOS repos together
