[FLINK-6337][network] Remove the buffer provider from
PartitionRequestServerHandler
Currently, `PartitionRequestServerHandler` will create a `LocalBufferPool`
when the channel is registered. The `LocalBufferPool` is only used to get
segment size for creating read view in `SpillableSubpartition`, and the buffers
in the pool will not be used all the time, so it will waste the buffer resource
of global pool.
We would like to remove the `LocalBufferPool` from the
`PartitionRequestServerHandler`, and the `LocalBufferPool` in `ResultPartition`
can also provide the segment size for creating sub partition view.
This modification will not effect the current behavior and will get
benefits of saving buffer resources.
