Include creation of files for benchmarking Mountpoint in benchmarking script

[sauraank]

Tell us more about this new feature.

Currently, we first create the files and directories required for benchmarking manually (although using fio jobs) by following Running the Benchmark section of our benchmark script.
Once the files are created, we run the benchmark scripts fs_bench.sh.
Our benchmark script should itself have the step of creating required files and directories if it already does not exist. It would make benchmarking Mountpoint for users a much easier process.

Added this benchmarking script in #779 . So, closing this issue as it is resolved now.
