Multi-node control plane clusters

It is now easy to get a multi-node control plane cluster. This release ships with an example that will create a 3-node control plane cluster with 1 worker node in a single availability zone. This is a small step towards cluster-api-provider-aws supporting highly availble clusters with minimal configuration. It is possible to create a highly available cluster, but much of the leg work is manual. Please see documentation for more information on how to create highly available clusters

Reliabilty

Previous releases had some issues with clusters getting stuck while being created. That was due to over-eagerness in reconciling the infrastrucutre. The code now only reconciles things when something has changed.

A good number of nil derefence errors have been cleaned up so you should be seeing fewer stack traces in your logs.

Supported Kubernetes versions

This release adds support for a few more Kubernetes versions including v1.14.0 and v1.14.1. You can find a complete list here.

Custom AMIs

Support has been added for custom AWS organizational IDs which allows you to upload your own AMIs to your own organization and use those to launch instances from.

Root device size customization

A configuration option for an AWS image's root device size has been added.
