Cancel the API Key when an environment is deleted

**Is your feature request related to a problem? Please describe.**

It is more of an oversight. Whenever an Environment is deleted within a project the API still returns calls if the key is provided.

**Describe the solution you'd like**

We should delete the API key along with the environment.

**Describe alternatives you've considered**

Maybe we want to wait for a period before deleting the API key or do a soft delete of sorts in the case the Env needs to be restored.

**Additional context**
