[Enhancement]: Add capacity-reservation-options flag to on-demand-options in Resource aws_ec2_fleet

[dkheyman]

Description

Currently, the aws_ec2_fleet on-demand-options specification only supports allocation_strategy flags. Support for capacity-reservation-options was released a good amount of time ago to specify that the EC2 fleet needs to take advantage of capacity reservations specified in the Launch Template of the fleet specification.

I would like to add support for capacity_reservation_options as indicated in the EC2 CreateFleet API.

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

aws_ec2_fleet

Potential Terraform Configuration

resource "aws_ec2_fleet" "example" {
  type = "instant"
  launch_template_config {
    launch_template_specification {
      launch_template_id = aws_launch_template.example.id
      version            = aws_launch_template.example.latest_version
    }
  }

  target_capacity_specification {
    default_target_capacity_type = "on-demand"
    total_target_capacity        = 3
  }

  on_demand_options {
    capacity_reservation_options = {
        "usage-strategy" = "use-capacity-reservations-first"
    }
  }
}
