feat: Support setting allowed IPv6 CIDR blocks
Description
Add an input allowed_ipv6_cidr_blocks
to set ipv6_cidr_blocks
in the cidr_ingress
security group.
Motivation and Context
In the last release, the network_type
input was introduced.
As allowed_cidr_blocks
is assigned to cidr_blocks
and this only accepts IPv4 networks, we need a similar way to set the IPv6 CIDR blocks in the cidr_ingress
security group when network_type = "DUAL"
is used.

How Has This Been Tested?
I have tested this change with our in-house terraform codebase.
I noticed that when I am creating a new cluster, I get this error (Terraform 1.3.0):
| Error: Invalid count argument
β
β on ../../terraform-aws-rds-aurora/main.tf line 348, in resource "aws_security_group_rule" "cidr_ingress":
β 348: count = local.create_cluster && var.create_security_group && (length(var.allowed_cidr_blocks) > 0 || length(var.allowed_ipv6_cidr_blocks) > 0) ? 1 : 0
β
β The "count" value depends on resource attributes that cannot be determined until apply, so Terraform cannot predict how many instances will be created. To work around this, use the -target argument to first apply only the resources that the count depends on.
