CloudFormation snippet to create a VPC to be used for lambda functions. Qualities of the VPC:

• 4 subnets: 2 public, 2 private (lambda functions should be attached to the private ones).
• 2 Elastic IPs that can be used to identify traffic coming from lambda functions (e.g. for firewall holes).
• Security group that can be used for lambda functions.

Notes:

• uses regions us-east-1a, us-east-1b
• uses ip block of 10.15.0.0/16 for VPC
