----------------------------------

Perf Test
Write 1000W rows to table_put_10B_1000w,  key=10B length, value=10B length, 64K 
hfileblock size.
Use ycsb to test the performance.
Only one regionserver, one client(and one thread), and run client on the 
regionserver's machine, result is:
Throughput(ops/sec), 9034     NONE
Throughput(ops/sec), 12817   ROW_INDEX_V1


> A new HFileBlock structure for fast random get

> HFileBlock store cells sequential, current when to get a row from the block, 
> it scan from the first cell until the row's cell.
> The new structure store every row's start offset with data, so it can find 
> the exact row with binarySearch.
