## What changes were proposed in this pull request? An option that limits the file stream source to read 1 file at a time enables rate limiting. It has the additional convenience that a static set of files can be used like a stream for testing as this will allows those files to be considered one at a time. This PR adds option `maxFilesPerTrigger`. ## How was this patch tested? New unit test Author: Tathagata Das <tathagata.das1565@gmail.com> Closes #14094 from tdas/SPARK-16430.
