(elasticloadbalancingv2): Incorrect validation on NetworkLoadBalancer.configureHealthCheck()

[ryparker]

The NetworkLoadBalancer's configureHealthCheck() method is incorrectly throwing a validation error when provided a valid protocol and the same value for both interval and timeout.

Error: Healthcheck interval 10 seconds must be greater than the timeout 10 seconds

This rule only applies to Application Load Balancers and not Network Load Balancers.

Reproduction Steps

const app = new cdk.App();
const stack = new cdk.Stack(app, 'Stack');
const vpc = new ec2.Vpc(stack, 'VPC', {});


new elbv2.NetworkTargetGroup(stack, 'TargetGroup', {
  vpc,
  port: 80,
  healthCheck: {
    interval: cdk.Duration.seconds(10),
    timeout: cdk.Duration.seconds(10),
    protocol: protocol,
  },
});

What did you expect to happen?

No validation errors.

What actually happened?

Error: Healthcheck interval 10 seconds must be greater than the timeout 10 seconds
