Li Lu updated YARN-4219:
    Attachment: YARN-4219-trunk.001.patch

Upload a patch to add the leveldb cache storage. To organize this storage, I 
refactored MemoryTimelineStore, moved the abstract logic to operate on a 
general map of entities into a new MapTimelineStore. Both MemoryTimelineStore 
and LevelDbCacheTimelineStore are MapTimelineStores, communicating through the 
abstract logic through a TimelineStoreMapAdapter.

> We need to have an "offline" caching storage for timeline server v1.5 after 
> the changes in YARN-3942. The in memory timeline storage may run into OOM 
> issues when used as a cache storage for entity file timeline storage. We can 
> refactor the code and have a level db based caching storage for this use 
> case.
