The v9.0 release contains backwards-incompatible changes.
This update requires upgrading the minimum provider version from 4.45 to 4.50.
The edge_security_policy object attribute and its nested attributes within the [backends] variable (https://github.com/terraform-google-modules/terraform-google-lb-http/blob/cb15ed7391f1bbcc4fdb6d55ee5703ca0d47447a/variables.tf#L81) is now available. It is optional.
The quic variable now takes true, false, or null which corresponds to HTTP/3 and Google QUIC being enabled, both disabled, and HTTP/3 enabled only. Defaults to null.
