(apigateway.RequestAuthorizer): (Removing Cache TTL does not reset to default value of 300s)

[bpauwels]

Describe the bug

If you create a custom authorizer and set resultsCacheTtl to any value other then 300s, then later remove the property, I would expect it to reset to the default of 300s. Instead, it remains at the latest set value.

Expected Behavior

TTL is reset to the default value of 300s

Current Behavior

TTL remains at the previously set value

Reproduction Steps

Reproduction Steps:

const authorizer = new RequestAuthorizer(this, "LambdaAuthorizer", {
      handler: authorizerHandler,
      resultsCacheTtl: cdk.Duration.seconds(301),
      identitySources: [
        IdentitySource.header("someheader"),
      ],
    });

Deploy this, then change it to

const authorizer = new RequestAuthorizer(this, "LambdaAuthorizer", {
      handler: authorizerHandler,
      identitySources: [
        IdentitySource.header("someheader"),
      ],
    });
