> In order to persist maintenance schedules across failovers of the master, the schedule information must be kept in the replicated registry.
> This means adding an additional message in the Registry protobuf in src/master/registry.proto.  The status of each individual slave's maintenance will also be persisted in this way.
> {code}
> message Maintenance {
>   message HostStatus {
>     required string hostname = 1;
>     // True if the slave is deactivated for maintenance.
>     // False if the slave is draining in preparation for maintenance.
>     required bool is_down = 2;  // Or an enum
>   }
>   message Schedule {
>     // The set of affected slave(s).
>     repeated HostStatus hosts = 1;
>     // Interval in which this set of slaves is expected to be down for.
>     optional Unavailability interval = 2;
>   }
>   message Schedules {
>     repeated Schedule schedules;
>   }
>   optional Schedules schedules = 1;
> }
> {code}
> Note: There can be multiple SlaveID's attached to a single hostname.
