[aws-events] Support AWS::Event::Archive

[baxang]

The package https://github.com/aws/aws-cdk/tree/master/packages/%40aws-cdk/aws-events does not have Archive which was recently added.

Use Case

The resources are

Proposed Solution

I propose implementing constructs for the aforementioned resources. The implemented construct would look like:

const eventBus = new events.EventBus(this, 'MyEventBus', { eventBusName: 'my-event-bus' });
new events.Archive(this, 'EventArchive', {
  description: string,
  eventBus: eventBus,
  retention: cdk.Duration.days(10),
  eventPattern: { /* JSON */ },
});

Meanwhile, there's a workaround using cdk.CfnResource as the CDK documentation suggests

• https://docs.aws.amazon.com/cdk/latest/guide/cfn_layer.html

new cdk.CfnResource(this, 'EventArchive', {
      type: 'AWS::Events::Archive',
      RetentionDays: 30,
      SourceArn: `arn:aws:events:${this.region}:${this.account}:event-bus/default`
});

We could also add an archive method on the EventBus itself (and available as part of the IEventBus interface since it's a separate resource and could be added on an imported resource) since it's the only resource it can be applied to.

const eventBus = new events.EventBus(this, 'MyEventBus', { eventBusName: 'my-event-bus' });

eventBus.archive({
  description?: string, // Should have a generated default
  retention: cdk.Duration.days(10), // Should have a default retention
  eventPattern: { /* JSON */ },
});
