(integ-tests): Set environment for Deploy Assert Stack

[dontirun]

Describe the feature

Allow setting the AWS environment (account/region) for the deploy assert stack

Use Case

I have a construct that uses ELBv2 access logging. ELBv2 access logging requires setting the region for the cdk environment. As showcased by this error

Error: Region is required to enable ELBv2 access logging

After setting the environment, I received the following error when I attempted to pass a reference to an Api Call in the Integ Test

Error: Stack "foo/DefaultTest/DeployAssert" cannot consume a cross reference from stack "bar". Cross stack references are only supported for stacks deployed to the same environment or between nested stacks and their parent stack

Proposed Solution

Allow setting the cdk environment in IntegTestProps

Other Information

No response

Acknowledgements

• I may be able to implement this feature request
• This feature might incur a breaking change

CDK version used

2.41.0

Environment details (OS name and version, etc.)

Osx

@dontirun can you provide an example of the integ test where you see the behavior?

[dontirun]

import * as cdk from 'monocdk';
import * as ec2 from 'monocdk/aws-ec2';
import * as elbv2 from 'monocdk/aws-elasticloadbalancingv2';
import * as s3 from 'monocdk/aws-s3';
import * as integ from 'monocdk/integ-tests';


const app = new cdk.App();

const stack = new cdk.Stack(app, 'stack',
    {
        env: { region: 'us-west-2' }
    })

const nlb = new elbv2.NetworkLoadBalancer(stack, 'nlb', { vpc: new ec2.Vpc(stack, 'vpc') })
// requires region to be set
nlb.logAccessLogs(new s3.Bucket(stack, 'logbucket'))


const test = new integ.IntegTest(app, 'integ', {
    testCases: [stack],
    regions: ['us-west-2'],
});

test.assertions.awsApiCall('Elbv2', 'describeLoadBalancers', {
    Names: [nlb.loadBalancerName]
});

app.synth();

Error: Stack "integ/DefaultTest/DeployAssert" cannot consume a cross reference from stack "stack". Cross stack references are only supported for stacks deployed to the same environment or between nested stacks and their parent stack

I'm giving a CDKv1 example here because this issue is preventing me from using v2 (without a hacky patch)

@dontirun thanks for the example, the makes perfect sense and we should definitely add this.
