Create an Ocean Spark cluster from scratch

This example shows how to create a VPC and an EKS cluster inside of it. The EKS cluster is then imported into Ocean and Ocean Spark.

In this example, the VPC is a "private VPC". It contains:

private subnets using a NAT gateway for egress. That's where the nodes and pods will go.
public subnets. That's where the load balancers and other exposed public IPs will go.

Additionally, the VPC has the following tags to be suitable for an EKS cluster:

kubernetes.io/cluster/<eks-cluster-name> = shared on the VPC itself, where <eks-cluster-name> is the name of the EKS cluster that will use this VPC. This tag should not be necessary since Kubernetes 1.19. We recommend to add it anyway.
kubernetes.io/cluster/<eks-cluster-name> = shared on all subnets.
kubernetes.io/role/elb = 1 on all public subnets.
kubernetes.io/role/internal-elb = 1 on all private subnets.

All required inputs are described in variables.tf.
