[Enhancement]: Elastic Network Interface configurable idle timeout for connection tracking

[flipsed]

Description

In November last year, aws introduced configurable idle timeout on the network interfaces. It would a great enhancement to be able to customise this in the aws_network_interface resource.

Affected Resource(s) and/or Data Source(s)

aws_network_interface

Potential Terraform Configuration

resource "aws_network_interface" "test" {
  subnet_id       = aws_subnet.public_a.id
  private_ips     = ["10.0.0.50"]
  security_groups = [aws_security_group.web.id]
  idle_timeout    = 432000

  attachment {
    instance     = aws_instance.test.id
    device_index = 1
  }
}

in this blog post AWS recommends tuning the timeout all the way down to 45s, given the a 2h default timeout for idle TCP connections is very high https://aws.amazon.com/blogs/networking-and-content-delivery/implementing-long-running-tcp-connections-within-vpc-networking/

Hi, is there an update? We're also needing to customize our Idle connection tracking timeout via Terraform.
