Support private_dns_name_options

[israel-anaya]

Description

When creating a new EC2 instance via the web console you have the option to choose the hostname type for the new instance - options are either IP name by default (ip-172-26-0-1.eu-west-3.compute.internal) or Resource name (i-0f0ccc1aa12371b73.eu-west-3.compute.internal). It should be possible to set this option in terraform.

Potential Terraform Configuration

module "ec2_instance" {
source = "terraform-aws-modules/ec2-instance/aws"
...
private_dns_name_options {
hostname_type = "resource-name" | "ip-name"
}
...
}

I think this module is missing this config:
https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/instance.html#private-dns-name-options

Yes would be nice to support it, right now the plan shows a diff

      - private_dns_name_options {
          - enable_resource_name_dns_a_record    = false -> null
          - enable_resource_name_dns_aaaa_record = false -> null
          - hostname_type                        = "ip-name" -> null
        }
