Serverless_negs module: Quic - No option to disable HTTP/3 advertising

[sakthivel-pro]

TL;DR

With the recent communication from GCP, quicOverride=NONE mode will advertise support for HTTP/3 to our clients. Providing Terraform config quic = false is updated as quicOverride=NONE. Deadline for the rollout is March 21, 2022.

A new option is required to disable HTTP/3 advertisement or by default quic = false should disable the HTTP/3 mode. Possibly change the data type from boolean to string to support different options.

@sakthivel-tw Happy to review a PR updating this.

@sakthivel-tw Setting quic = false should send null value. Provider default value is None which is equivalent of DISABLE. Can you plz confirm if this is working fine?

@imrannayer The Provider default value NONE is acting as the same as ENABLE. (I can confirm on my project HTTP/3 is advertized when set to NONE) https://cloud.google.com/load-balancing/docs/https#configuring-http3

I think making false map to DISABLE will retain the original behaviour prior to March 21, 2022

[s3i7h]

Apprarently the provider hasn't updated the description yet to match the actual behaviour https://github.com/hashicorp/terraform-provider-google-beta/blob/acc18edf88435e6f42081622dd0991e6102c31de/google-beta/resource_compute_target_https_proxy.go#L90-L92

@yu-ichiro can you plz create an issue for provider to update the doc?

[quic_override](https://registry.terraform.io/providers/hashicorp/google/latest/docs/resources/compute_target_https_proxy#quic_override) - (Optional) Specifies the QUIC override policy for this resource. This determines whether the load balancer will attempt to negotiate QUIC with clients or not. Can specify one of NONE, ENABLE, or DISABLE. If NONE is specified, uses the QUIC policy with no user overrides, which is equivalent to DISABLE. Default value is NONE. Possible values are: NONE, ENABLE, DISABLE.
