In 'HadoopMapReduceCommitProtocol', task output files are generated ahead
instead of calling
`org.apache.hadoop.mapreduce.lib.output.FileOutputFormat#getDefaultWorkFile`,
which uses the `mapreduce.output.basename` as the prefix of output files.
In this pull request, we modify the
`HadoopMapReduceCommitProtocol.getFilename` method to also look up this config
instead of using the hardcoded 'part'.
### Why are the changes needed?
Given a custom file name is a useful feature for users. They can use it to
distinguish files added by different engines, on different days, etc. We can
also align the usage scenario with other SQL on Hadoop engines.
### Does this PR introduce _any_ user-facing change?
Yes, a Hadoop configuration 'mapreduce.output.basename' can be used in file
datasource output files
### How was this patch tested?
new tests
