Description

For Profiling FileIO events, there are 2 keys:

DFS_DATANODE_ENABLE_FILEIO_PROFILING_KEY for enabling the hooks
DFS_DATANODE_FILEIO_PROFILING_SAMPLING_FRACTION_KEY for setting the sampling fraction

We can instead have only the sampling fraction key and set it to 0 if we want to disable profiling.
