(aws-ecs): add Cluster.fromLookup()

[misterjoshua]

I'd like the L2 ECS Cluster construct to have a fromLookup() that acts like many of the other L2 construct fromLookup() methods.

Use Case

I want to look up an ECS cluster defined in another stack.

Proposed Solution

// Look up the cluster
const cluster = ecs.Cluster.fromLookup(this, 'Cluster', {
  tags: { Name: 'OtherStack/Whatever/Here' },
});

// Create an EC2-based service in the looked-up cluster
new ecs.Ec2Service(this, 'Service', {
  cluster,
  //...
});

+1 on wanting this implemented

Why do we need fromLookup() given we already have fromClusterAttributes()?

aws-cdk/packages/aws-cdk-lib/aws-ecs/lib/cluster.ts

Line 110 in f470271

public static fromClusterAttributes(scope: Construct, id: string, attrs: ClusterAttributes): ICluster {

Can someone share the use cases?
