Support carbon forecasting in timeshift (#327)

* Remove task from scheduler bookkeeping after failure

* Support carbon forecasting in timeshift

* Register scheduler and carbonmodel in context

* Preliminary working task stopping; carbon intensity bug

* Working carbon based stop. Two timeshift thresholds

* Add a pause state task and guest

* Move task stopper to allocation spec

* Start tracking num pauses
