Add AWS module and docs

[dghubble]

Add AWS module as "alpha". Its not mature like the others (which I've used for years), but the basics are there:

• Basic control plane
• Pod-to-pod networking
  • Flannel (900-1000 MB/s pod-to-pod, varies)
  • Calico (~350MB/s with MTU 1480, 900-1000MB/s pod-to-pod with MTU to 8981)
• BGP Peering
• Load balanced apiserver, ingress
• Firewalls
• IPv6
• Change Launch Configuration -> Rollout
• kubectl (usual suspects)
  • logs
  • port-forward
  • exec
• Nice node names (haven't decided what's desired here yet)

Addons

• Nginx Ingress
• Dashboard
• Heapster
• CLUO

Comments / Areas to Improve

• AWS networking in rather subpar compared with Google Cloud. Lower peak bandwidth and varies wildly.
• AWS provisioning is much slower because of the DNS -> ELB -> ASG setup (i.e. 10-20 min). As part of deprecating self-hosted etcd, controllers will be statically provisioned and this will be sped up greatly.
• Cluster deletion is also much slower than other platforms (i.e. 8 min). Feels sluggish.
• Kubernetes AWS integrations aren't enabled. I'll get to them, just not a major priority since my workloads are agnostic.
