slapos_crm: Move alarm into SoftwareInstance_getReportedErrorDict

   Drop the specific alarm and update SoftwareInstance_getReportedErrorDict to issue a ticket if the user has an instance on a 'close/forever' compute node.

   Keep in mind that in the future, we can use "close for termination" in addition to close forever to create tickets when a computer is going to be removed, so the administrator or user can take actions in relation to it.
