Serverless_negs module: once https_redirect is enabled, it can't be disabled

Hi!

I am using negs module: GoogleCloudPlatform/lb-http/google//modules/serverless_negs
Once the https redirection is enabled by setting https_redirect = true it cant be disabled later, because of following error:
Error when reading or editing UrlMap: googleapi: Error 400: The url_map resource 'projects/XYZ/global/urlMaps/XYZ-https -redirect' is already being used by 'projects/XYZ/global/targetHttpProxies/XYZ-http-proxy', resourceInUseByAnotherResource

You also can't update the managed_ssl_certificate_domains for the same reason.

Workaround in the meantime:

Manually delete the -https-redirect entries (one-by-one) in Load balancing then re-run terraform apply to recreate the HTTP frontend configs.

+1 on this. Flagging for followup. Also see a similar behavior when re-naming a managed cert domain.
