Describe the feature

In L2 Construct, the following target group attributes are not supported yet.

• target_group_health.dns_failover.minimum_healthy_targets.count - The minimum number of targets that must be healthy. If the number of healthy targets is below this value, mark the zone as unhealthy in DNS, so that traffic is routed only to healthy zones. The possible values are off or an integer from 1 to the maximum number of targets. The default is off.
• target_group_health.dns_failover.minimum_healthy_targets.percentage - The minimum percentage of targets that must be healthy. If the percentage of healthy targets is below this value, mark the zone as unhealthy in DNS, so that traffic is routed only to healthy zones. The possible values are off or an integer from 1 to 100. The default is off.
• target_group_health.unhealthy_state_routing.minimum_healthy_targets.count - The minimum number of targets that must be healthy. If the number of healthy targets is below this value, send traffic to all targets, including unhealthy targets. The possible values are 1 to the maximum number of targets. The default is 1.
• target_group_health.unhealthy_state_routing.minimum_healthy_targets.percentage - The minimum percentage of targets that must be healthy. If the percentage of healthy targets is below this value, send traffic to all targets, including unhealthy targets. The possible values are off or an integer from 1 to 100. The default is off.
