[2/7] mesos git commit: Changed the nested ContainerID from hashmap to hashset in memory.

[ji...@apache.org]

Changed the nested ContainerID from hashmap to hashset in memory.

To support nested containers, each container should maintain a list
of its children containers in structure. The tree-like structure is
not necessary though. We just need to keep a flat hashset for nested
containers.
