Description
### Describe the bug
We are using AwsCustomResource to execute s3:deleteBucketInventoryConfiguration on delete. We have observed sporadic failures that cause CloudFormation to end up hitting its one hour timeout because the custom resource never responds.
Looking in the logs for the custom resource lambda that CDK autogenerates, we see the task repeatedly time out after 120 seconds. There are no other logs. As per CloudTrail, the call to S3 is never even made.
### Expected Behavior
The custom resource should work.
### Current Behavior
It sporadically gets stuck and never responds.
### Reproduction Steps
```python
custom_resources.AwsCustomResource(
scope,
id,
install_latest_aws_sdk=True,
policy=custom_resources.AwsCustomResourcePolicy.from_statements([
iam.PolicyStatement(
actions=["s3:PutInventoryConfiguration"],
resources=[],
),
]),
on_delete={
"service": "S3",
"action": "deleteBucketInventoryConfiguration",
"parameters": {
"Bucket": ,
"Id": ,
}
}
)
```

Contributor guide
Research direction
Start at the AwsCustomResource entry point and reproduce the on_delete call for S3 deleteBucketInventoryConfiguration with install_latest_aws_sdk enabled. Inspect the generated custom resource Lambda around the repeated 120-second task timeouts and verify that the resource responds reliably and the S3 call is reached.
