Description

Add enum type into RevocableInfo:

• Framework need to assign RevocableInfo when launching task; if it’s not assign, use reserved resources. Framework need to identify which resources it’s using
• Oversubscription resources need to assign the type by Agent (MESOS-3930)
• Update Oversubscription document that OO has over-subscribe the Allocation Slack and recommend QoS to handle the usage slack only. (MESOS-3889)

message Resource {
  ...
  message RevocableInfo {
   enum Type {
     // Under-utilized, allocated resources.  Controlled by
     // oversubscription (QoSController & ResourceEstimator).
     USAGE_SLACK = 1;

     // Unallocated, reserved resources.
     // Controlled by optimistic offers (Allocator).
     ALLOCATION_SLACK = 2; 
   }

   optional Type type = 1;
  }

  optional RevocableInfo revocable = 9;
