one-shot-onlyIf a guest request has a specific key in its user-data field, this policy would cancel the request should it enter routing for the second time.
In other words, when the first routing and provisioning attempt fails, there would be no second attempt.
The key to look for in user-data can be set via route.policies.one-shot-only.label knob, or ARTEMIS_ROUTE_POLICIES_ONE_SHOT_ONLY_LABEL
environment variable.
By default, it is set to ArtemisOneShotOnly.
