[SPARK-15958] Make initial buffer size for the Sorter configurable
## What changes were proposed in this pull request?
Currently the initial buffer size in the sorter is hard coded inside the
code and is too small for large workload. As a result, the sorter spends
significant time expanding the buffer size and copying the data. It would be
useful to have it configurable.
## How was this patch tested?
Tested by running a job on the cluster.
