VPC

This is a module which simplifies setting up a new VPC and getting it into a useful state:

• Sets up the route tables for the public and private subnets you specify.
• Enables IPv6 for the VPC and allocates a /64 block for each of the public and private subnets.
• Creates up an internet gateway and route table for your public subnets.
• Creates a NAT gateway for your private subnets if desired (requires public subnets).
• Creates an egress only internet gateway for IPv6 traffic outbound from the private subnets.
• Adds the tag type to each subnet with the value of either public or private.
• Adds VPC Gateway Endpoints for s3 and dynamodb

Note that, if create_nat_gateways is enabled, each private subnet has a route table which targets an individual NAT gateway when accessing the internet over IPv4, which means that all instances in a given private subnet will appear to have the same static IP from the outside.
