Configurable VPC CIDR blocks
Added
- Enable using a custom CIDR block for the VPC (optional)
- Make the public subnets' CIDR blocks configurable (optionally)
- Make the private subnets' CIDR blocks configurable (optionally)
- Add new variables to vpc's README's list of optional inputs
Fixed
- Fix typo in vpc README example
Note:
I set the defaults to match the calculated values we have been using, so that this should be a non-breaking change (unless someone is using more than 4 availability zones, which we aren't, as far as I am aware).
