Code-manager hooks: Make URL parameters configureable

[bastelfreak]

Use Case

Code-Manager has support for post environment hooks: https://www.puppet.com/docs/pe/2023.8/code_mgr_customizing#config_post_env_hooks

And there's an API endpoint for the classifier to refresh classes: https://www.puppet.com/docs/pe/2023.8/update_classes_endpoint

The classifier API can take an optional parameter for a specific environment. But I didn't see an option in the code manager config to set this. So calling the classifier API will always trigger a full refresh, which is quite resource intensive.

Describe the Solution You Would Like

Add an option to code-manager to use the deployed environment in the hook url.
