OneTimeTrigger

A trigger that triggers only once during a deployment.

In contrast to ImmediateTrigger, which triggers every time the app is (re)started, this OneTimeTrigger only triggers once during the life-time of a deployment. Useful for triggering e.g., a demographic survey or collecting device information.
