Implement 60 day time limit for issues.

[muratmaga]

Once approved, each issue should be closed at 60 days and all user data (instance+volume) should be deleted, unless user takes an action (renewal request, /renew command).

60 days after the instance is created (what to do if instance is recreated for any reason??? Look at the time stamp of first /create command?), we should send an email to the issue owner indicating their 60 day usage time is over and that they have 7 days (grace period) to take action. They can take three actions:

1. Do nothing. The instance and volume will be deleted and issue will be closed at end of grace period.
2. Access the system to download their data within the grace period, then do nothing. Outcome will be same as above.
3. Request for another 60 days by giving the /renew command on the issue page within the grace period.

I assigned this as release 1.0 milestone, but it is less critical than the other and can be be implemented a little later.

• Typing /renew will change a from lifespan: 60days to lifespan: 120days
• At (lifespan - 7 days), send an email + add comment on the issue to give a chance to type /renew
