Description

Added support for dynamic modules from map variables, for example:
(Full example in the tests folder)

dynamic "ingress" {
    for_each = var.http_headers
    content {
      rule_no    = ingress.value.num  # or ["num"]
      protocol   = ingress.value.protoc  # or ["protoc"]
      action     = "allow"
      cidr_block = ingress.value.values  # or ["values"]
      from_port  = 22
      to_port    = 22
    }
  }
