[aws-eks] Add Bottlerocket support for aws-eks

[pahud]

Bottlerocket is currently in public preview stage but already supports Amazon EKS with Kubernetes 1.15. Would be great if we can support it in the aws-eks construct.

Use Case

To make Bottlerocket setup easier for AWS CDK users.

Proposed Solution

At this moment, Amazon EKS managed nodegroup only supports Amazon Linux. The only option would be unmanaged nodegroups. We can enable the Bottlerocket support by specifying the AMI from the provided SSM path or simply just create a new enum for the capacityOptions.

machineImageType?: EksMachineImageType in the capacityOptions

for example

new eks.Cluster(scope ,id, { machineImageType: EksMachineImageType.BOTTLEROCKET });

If specified, we get the latest Bottlerocket AMI and assign to the machineImage property for the AutoScalingGroup under the hood. Otherwise, the default Amazon Linux will be selected.

machineImage: new EksOptimizedImage({
