[Tools] Rebalance data among different disks
There already existed a good algorithm to make data distribute
in different disks balancely. But when a host adding more new
disks, Kudu can not rebalance the data among disks immediately.
This patch offer a tool to rebalance data among different disks.
It firstly statistics of the number of tablets in disks. Then
move the tablets from the disk owning most tablets to the less
one. In reality, it migrates blocks from one disk to the other.
