replace VPC data with variable

[dudicoco]

Hi,

Currently, the VPC CIDR block is pulled from the VPC data:

terraform-aws-client-vpn-endpoint/main.tf

Lines 42 to 44 in 35e1693

	data "aws_vpc" "this" {
	id = var.endpoint_vpc_id
	}

This is problematic when using terragrunt run-all to set up an entire stack (vpc + client vpn etc.) as the plan will fail since the VPC doesn't exist yet:

│ Error: no matching EC2 VPC found
│
│   with module.vpn.data.aws_vpc.this,
│   on .terraform/modules/vpn/main.tf line 42, in data "aws_vpc" "this":
│   42: data "aws_vpc" "this" {
│

I assume this would also happen when running normal terraform plan (without terragrunt) with vpc + client vpn in the same main.tf, but I didn't test it.

The solution is to remove the VPC data resource and add a new variable endpoint_vpc_cidr_block.
Will be happy to contribute a PR.
