Burstable workloads with OKD on ARM

Uses OpenShift Ansible and an AWS CloudFormation template to build OKD on ARM EC2, spinning 3-node cluster (1 master + 2 workers) from a fedora/centos image on a1.4xlarge instances; master performance on ARM is slow so Python2 and RPM installs are required for some components. Demonstrates autoscaling with auto scaling groups and scalar.py plus life cycle hooks to drain and register nodes, claims ~45% cost savings for burstable workloads, and shows the setup mostly works though transient failures and rate limits occur.
