Add option to control `enable_exactly_once_delivery` for subscriptions.

[ttacon]

TL;DR

Currently, enabling exactly once delivery is a preview feature for GCP PubSub subscriptions. I'm curious if y'all are open to adding this flag while it's in a preview state to this module (the official provider supports it).

Terraform Resources

The official pubub_subscription provider supports the enable_exactly_once_delivery.

Detailed design

Implementing this should be a similar change to this one here.

The only major constraint would be that enable_exactly_once_deliver and enable_message_ordering are mutually exclusive. However, handling that doesn't feel like this module's responsibility (the provider should handle it, which it doesn't).

Any other information that I can provide here?

Howdy folks - checking in again, would this be a change that we'd be open to taking in?

Hello,

I would also like to +1 this. I have the code changes that I've made myself, however it's annoying to apply the changes after init-ing the module.

Hi @hdavila146 - Thanks for reaching out. The standard practice is to create your own fork of this repo and upload your changes to a branch on your fork. You should then be able to create a pull request from the branch in your fork to this repository.

this is done in the @ttacon @notobsd2 commit 9b6b913
