Title: Eliminate CacheTracker

Replaces DAGScheduler's queries of CacheTracker with BlockManagerMaster
queries. This may have negative performance implications; I have not tested for them.

The remaining CacheTracker functionality of locally coordinating the computation of cachable RDDs is moved to a new class called CacheManager.
