Manage the lifecycle of systems

During the sysadmin meeting in Brussels we discussed our infrastructure. Systems are managed by service admins/owners. They sometimes disappear or services become irrelevant. This means we have systems without proper owner which are rotting over time.

To better handle such systems we decided that systems like $host.torproject.org should have an expiration date which is initially one or two years in the future. When the expiration date is near the service owner receives an email informing about the possible shutdown and the means to prevent it (write an email answer to tpa). If the mail is answered the expiration date will be prolonged. If not, the system will be deactivated. The deactivation can easily be revoked. However after some more time without any feedback the host will be decommissioned.

This ticket is to track the several steps for implementing this new policy.
