Terraform module to create network load balancers

Module usage:

 module "nlb" {
   source         = "git::https://github.com/UKHomeOffice/acp-tf-nlb?ref=master"

   name            = "my-service"
   environment     = "dev"            # by default both Name and Env is added to the tags
   dns_zone        = "example.com"
   vpc_id          = "vpc-32323232"
   tags            = {
     Role = "some_tag"
   }
   # A series of tags applied to filter out the source subnets, by default Env and Role = elb-subnet is used
   subnet_tags {
     Role = "some_tag"
   }

   listeners = [
     {
       port         = "80"
       target_port  = "30200"
       target_group = "compute"
     },
     {
       port         = "443"
       target_port  = "30201"
       target_group = "compute"
     }
   ]
 }
