CreateTransitGatewayVpcAttachment
Attaches the specified VPC to the specified transit gateway.
If you attach a VPC with a CIDR range that overlaps the CIDR range of a VPC that is already attached, the new VPC CIDR range is not propagated to the default propagation route table.
To send VPC traffic to an attached transit gateway, add a route to the VPC route table using CreateRoute.
