> Abstract an ByteBuffAllocator to allocate/free ByteBuffer in ByteBufferPool

> Now  our read/write path allocate ByteBuffer from the ByteBufferPool, but we 
> need consider the minSizeForReservoirUse for better utilization, those 
> allocate/free api are some static methods,  not so good to use. 
> For HBASE-21879,  we need an universal ByteBuffer allocator to manage all the 
> ByteBuffers through the entire read path, so create this issue. 
> Will upload a patch to abstract an ByteBufAllocator.
