      Implement Phase 2 of the merge chunk routine according to the technical design

      • Move small chunks (< 25 % targetChunkSize) to larger contiguous chunks
      • Might have produced oversized chunks > target chunk size, so we split them
      • Convergence: If no more operations are queued inthen we reached convergence
      • return to the normal balancer mode
