Interface for classes that provide the connection-specification parts of a security group rule.

## Example

```ts
declare const loadBalancer: elbv2.ApplicationLoadBalancer;

const vpc = new ec2.Vpc(this, 'MyVPC');
const fleet = new codebuild.Fleet(this, 'MyProject', {
  computeType: codebuild.FleetComputeType.MEDIUM,
  environmentType: codebuild.EnvironmentType.LINUX_CONTAINER,
  baseCapacity: 1,
  vpc,
});

fleet.connections.allowTo(loadBalancer, ec2.Port.tcp(443));

const project = new codebuild.Project(this, 'MyProject', {
  environment: {
    fleet,
  },
  buildSpec: codebuild.BuildSpec.fromObject({
    // ...
  }),
  // Trying to configure a project-level VPC is an error, because this project
  // runs on the Fleet created above.
  // vpc,
});
```

```ts
new Port(props: PortProps)
```
