account, and import the subnet configuration. Looking up can be done by VPC
ID, but more flexibly by searching for a specific tag on the VPC.

The import does assume that the VPC will be *symmetric*, i.e. that there are
subnet groups that have a subnet in every Availability Zone that the VPC
spreads over. VPCs with other layouts cannot currently be imported, and will
either lead to an error on import, or when another construct tries to access
the subnets.

Subnet types will be determined from the `aws-cdk:subnet-type` tag on the
subnet if it exists, or the presence of a route to an Internet Gateway
otherwise. Subnet names will be determined from the `aws-cdk:subnet-name` tag
