AwsCustomResource doesn't regard lists for the outputPath parameter

[mmuller88]

Relates to #2825 where you could reduce the response using outputPath. That filter only applies for objects but responses can have lists as well. I am runnint into the 4k limit issue with accessing https://docs.aws.amazon.com/cli/latest/reference/ec2/describe-vpn-connections.html where that are lists.

Reproduction Steps

1. Create a Custom Resource with accessing https://docs.aws.amazon.com/cli/latest/reference/ec2/describe-vpn-connections.html

new AwsCustomResource(this, 'describeVpnConnections', {
            onCreate: {
                service: 'EC2',
                action: 'describeVpnConnections',
                parameters: {
                    VpnConnectionIds: [vpnConnection.vpnId]
                },
                outputPath: 'VpnConnection.Options',
                physicalResourceId: PhysicalResourceId.of(`${vpnConnection.vpnId}-describe`),
            },
            policy: AwsCustomResourcePolicy.fromSdkCalls({resources: AwsCustomResourcePolicy.ANY_RESOURCE})
        });

What did you expect to happen?

Response successfull and only Options are returned.

What actually happened?

Fails as response ist too long
