RHEL 7.4 Support

Tested 4 flavors of Ref Arch with 7.4

Noticed a incompatible change on Azure SKU for

RHEL

All templates passed test

Leasons Learned

Using the Single VM template sped up the move to

3.6 significantly

Workflow has now changed to develop new features

to single VM and then port to multiple VM

DevOps worked really well this sprint, allowing us to

pivot mid sprint, and address the version issues and

the rapid change of OCP in a better way.
