[FEATURE] Deprovision resources if wait_for_completion_timeout is exceeded

Is your feature request related to a problem?

As per current documentation, if wait_for_completion_timeout is exceeded for Provision API, execution continues asynchronously. As user of Provision API, I think it may be better to stop provisioning, and deprovision created resources, because timeout may indicate request should fail, which is more aligned with my expectation. Continuing execution asynchronously is actually same experience as calling Provision API without wait_for_completion_timeout.

What solution would you like?

Add one more param like fail_on_timeout:boolean. Default is false, which ensures backward compatibility. If value is specified as true, when wait_for_completion_timeout is exceeded, fail the request and deprovision the created resources.

What alternatives have you considered?

One alternative solution is to simply change existing behavior to fail the request and deprovision the created resources when timeout is exceeded, without adding fail_on_timeout param

Do you have any additional context?

N/A

Start with the Provision API behavior described in the issue and trace how wait_for_completion_timeout is handled when execution continues asynchronously. Clarify whether fail_on_timeout should be opt-in and how created resources are deprovisioned on timeout. Done means the chosen behavior is implemented while preserving the default backward-compatible behavior.
