Description of changes
Functional changes are in
_setDeploymentResource. All other changes were auto-fixed by the linter or me trying to make the linter happy while not bloating the PR too much.This change fixes the flakiness we have seen in
apigw.test.tswhere the default CORS headers are not included in 4xx and 5xx responses. This was caused because the REST API, default responses and REST API deployment are all separate CFN resources. The REST API deployment has an implicit dependency on the REST API, but the default responses must also be provisioned before the REST API deployment is provisioned. There was a race condition where sometimes the default responses would be provisioned in time and sometimes not. This PR adds an explicit dependency between the REST API deployment and the default response resourcesIssue #, if available

Description of how you validated changes
It's difficult to be 100% sure this fixes it because of the nature of intermittent failures, but I ran the test locally a few times and they all passed after this change
