Error deprovisioning a specific project for an ephemeral environment is not returned in API

Latest Version

I could reproduce the problem in the latest build

What happened?

When deprovisioning an ephemeral environment for a specific project (keeping the environment after deprovisioning), if the deprovisioning runbook cannot be run then the project is currently marked as "Deprovisioning Failed" and the API returns 200 OK.

This is unexpected as the action being performed by the user wasn't able to be done.

Reproduction

• Create a runbook to use for deprovisioning, setting it to only be runnable on a specific shared environment, meaning it cannot be run on an ephemeral environment.
• Configure project to use ephemeral environments and select the deprovisioning runbook.
• Create an ephemeral environment and deploy to it.
• Deprovision the environment, selecting to "Keep the environment after deprovisioning".

Error and Stacktrace

The project is marked as "Deprovisioning failed" and the API returns 200 OK instead of an error.

Release Note: Changes the API to deprovision an ephemeral environment for a specific project so that if the deprovisioning runbook can't be run a HTTP error is returned with the error message instead of setting the project to Deprovisioning Failed and returning 200 OK. Please update any custom usage of this API to reflect this.
