Issue MESOS-4772: TaskInfo/ExecutorInfo should include fine-grained ownership/namespacing
We need a way to assign fine-grained ownership to tasks/executors so that multi-user frameworks can tell Mesos to associate the task with a user identity (rather than just the framework principal+role). Then, when an HTTP user requests to view the task's sandbox contents, or kill the task, or list all tasks, the authorizer can determine whether to allow/deny/filter the request based on finer-grained, user-level ownership. Some systems may want TaskInfo.owner to represent a group rather than an individual user. That's fine as long as the framework sets the field to the group ID in such a way that a group-aware authorizer can interpret it.
