HDFS Federation: Rename BlockPool class to BlockPoolSlice 
----------------------------------------------------------

                 Key: HDFS-1674
                 URL: https://issues.apache.org/jira/browse/HDFS-1674
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: data-node
    Affects Versions: Federation Branch
            Reporter: Tanping Wang
            Assignee: Tanping Wang
            Priority: Minor
             Fix For: Federation Branch


HDFS Federation (porting):
The class BlockPool is poorly named as it does not represent an actual BlockPool, but rather
that slice of the overall BlockPool for which a single DataNode is responsible.  Renames BlockPool,
BlockPoolStorage, BlockPoolScanner to BlockPoolSlice*.  Moves BlockPookSlice out of FSDataSet
to a stand-alone class.  Updates references to these structures.  Other references to BlockPools
seem appropriate in the context of the code.
