Fix mount path and delete file for local hostpath

[anson627]

This pull request makes targeted updates to the fio deployment configuration and the fio benchmark execution script. The main changes are a modification to the mount path used by the fio container and the addition of an option to the fio command to ensure test files are cleaned up after execution.

Deployment configuration update:

• Changed the mountPath for the fio container from /mnt/nvme-raid to /mnt/data in volumes.yaml to reflect the correct storage location.

Fio benchmark execution improvement:

• Added the --unlink=1 option to the fio command in fio.py to automatically remove test files after the benchmark completes, helping to keep the storage clean.
