[tez] Fix initialization of MemoryManager.
The memory manager in Tez is currently initialized as if it were shared
between 10 concurrently executing tasks. This reduces the amount of memory
available to a single task.
Because the memory manager is only used by one task at a time, we should
configure it like that to avoid wasting memory.
