> Given a schedule, defined elsewhere, any resource offers to affected slaves must include
an Unavailability field.
> The maintenance schedule for a single slave should be held in [persistent storage|MESOS-2075]
and locally by the master.  i.e. In src/master/master.hpp:
> {code}
> struct Slave {
>   ... // Existing fields.
>   // New field that the master/allocator can access
>   Maintenances pendingDowntime;
> }
> {code}
> The new field should be populated via an API call (see [MESOS-2067]).
> The Unavailability field can be added to Master::offer (src/master/master.cpp).
> {code}
> offer->mutable_unavailability()->MergeFrom(slave->pendingDowntime);
> {code}
> Possible test(s):
> * PendingUnavailibilityTest
> ** Start master, slave.
> ** Check unavailability of offer == none.
> ** Set unavailability to the future.
> ** Check offer has unavailability.
