Klaus Ma updated MESOS-3892:
----------------------------
    Description: 
In the agent, add a helper function to get the list of the exeuctor using ALLOCATION_SLACK.

It's short term solution which is different the design document, because master did not have executor for command line executor. Send evicatble executors from master to slave will addess in post-MVP after MESOS-1718.

{noformat}
class Slave {
...
  // If the executor used revocable resources, add it into `evictableExecutors`
  // list.
  void addEvictableExecutor(Executor* executor);

  // If the executor used revocable resources, remove it from
  // `evictableExecutors` list.
  void removeEvictableExecutor(Executor* executor);

  // Get evictable executor ID list by `Resource::RevocableInfo::Type`.
  std::list<ExecutorID> getEvictableExecutors(
      Resource::RevocableInfo::Type type);

...

  // The map of evictable executor list. If there's not enough resources,
  // the evictable executor will be terminated by slave to release resources.
  hashmap<mesos::Resource::RevocableInfo::Type, std::list<ExecutorID>>
      evictableExecutors;
...
}
{noformat}


  was:

{noformat}
class Slave {
  ...
  // How the master currently keeps track of executors.
  hashmap<FrameworkID, hashmap<ExecutorID, ExecutorInfo>> executors;
  ...
  // Returns the list of executors that are using optimistically-
  // offered, revocable resources.
  list<ExecutorID> getEvictableExecutors() { ... }
  ...
}
{noformat}
