Balancer should not try to pair storages with different types

      Description

      This is a performance bug – Balancer may pair a source datanode and a target datanode with different storage types. Fortunately, it will fail schedule any blocks in such pair since it will find out that the storage types are not matched later on.

      The bug won't lead to incorrect results.
