> The master will need to do a number of things to implement the maintenance primitives:
> # For slaves that have a maintenance window:
> #* For unused resources, offers must be augmented with an Unavailability.
> #* For used resources, inverse offers must be sent.
> # For inverse offers that are declined, we must filter these before sending them again. We must also store the decline reason, guard against OOMing. 
> #* My hunch is that we'll not want to persist the reasons in the initial approach.
> # When the drain window is reached, we'll make a binary decision as to whether the slave was drained, based on whether it was empty.
> #* If drained, we deactivate this slave and store the fact that it was drained.
> #* If not drained, we leave this slave activated.
> # Recover the maintenance information upon failover.
