net-ilb-l7 module bug has mismatch of urlconfig parameters.

[CodyKurtz]

When configuring a URL map with the urlmap_config parameter on the net-ilb-l7 module, the Terraform apply will fail when specifying a route_rule. There is no default_url_parameter under route_rules. The parameter is url_redirect and is reflected in the url map variables file.

See the following links to see the mismatch.

https://github.com/GoogleCloudPlatform/cloud-foundation-fabric/blob/v21.0.0/modules/net-ilb-l7/urlmap.tf#L548

The following error is produced:

 

Planning failed. Terraform encountered an error while generating this plan.

@CodyKurtz would you mind sharing the module configuration so we can plug it into a test?

Thanks a lot for flagging this and doing the investigation!
