What

This pull request introduces a new Terraform configuration example for provisioning a Confluent Cloud enterprise cluster on Google Cloud Platform (GCP) with Private Service Connect (PSC). This example is necessary to provide users with a complete, runnable guide for setting up private, secure connectivity to Confluent Cloud within their GCP environment.

The implementation follows the established conventions of existing examples, mirroring the directory structure of the aws and azure enterprise examples and adhering to the GCP resource conventions from the dedicated cluster PSC example. Key changes include adding a new gcp-enterprise-example directory and configuring the necessary Terraform files (main.tf, variables.tf, outputs.tf) to manage the required resources.

Blast Radius

If something goes wrong with this pull request, the impact is minimal. This is a new example and not a change to the core provider functionality. The primary risk is that the example may not work as intended, potentially causing confusion for users attempting to follow it. It will not break existing user configurations or block any current customer operations, as it does not affect any existing resources, data sources, or import functions.

Test & Review

Yes, this pull request was tested from end to end using a GCP account. The verification process involved deploying all resources defined in the gcp-enterprise-example directory, including the Confluent Cloud enterprise cluster and the Private Service Connect (PSC) setup. All resources were successfully provisioned and then destroyed, confirming the example's functionality and ensuring it is a complete, runnable solution for users. This end-to-end test confirms that the provided Terraform example works as intended for setting up a private Confluent Cloud cluster on GCP.
