/*
* This sample builds and runs a console hosted application that would stop after 10 seconds.
* In practice, you would have another component in the application that takes a dependency on
* ILifetimeExpirationCheckpoint and calls ILifetimeExpirationCheckpoint.SetCheckpoint() to notify activity
* The LifetimeMonitorHostedService will see this activity and will keep the application alive
*
* An example is a component that consumes messages off of a queue such as RabbitMQ / SQS / others
* When a message is received, ILifetimeExpirationCheckpoint.SetCheckpoint() can be called to notify activity.
* - If another message is received within N seconds (specified using WithSlidingExpirationInterval), the same application
* instance will process it.
* - If no messages arrive in N seconds, the application terminates
