Description

Whenever a slave sees a persistent disk resource (in ExecutorInfo or TaskInfo) that is new to it, it will create a persistent directory which is for tasks to store persistent data.

The slave needs to do the following after it's created:
1) symlink into the executor sandbox so that tasks/executor can see it
2) garbage collect it once it is released by the framework
