As a platform engineer I want to get an ephemeral (short-lived, limited purpose) API key for meshStack in my building block run. This would enable me to interact with meshStack as part of a building block run (e.g. provision a new building block in the background) without needing almighty admin permissions. The UI should show in the marketplace when a building block uses this so it is transparent to users what side effect certain building blocks might have. It could show for examlpe "This building block has the permission to provision other building blocks in your workspace.". My use case is that I want to provide an "extension" of another building block. Rather than defining a dependency and having the user book both, I want to automatically create a Building Block via Terraform in the background.
