allow "lfs find --ost" to accept an OST range

    Description

      It would be convenient to allow specifying a range of OSTs to find objects on, like "lfs find /mnt/testfs -type f --ost 8-15". Currently, one has to specify all of the OSTs in a comma-separated list like "... --ost 8,9,10,11,12,13,14,15", which can be inconvenient for large OST lists. Using the bash range syntax like "{8..15}" doesn't work because this will expand to a space-separated list of indices.

            Hi ahkumarsmu, did you ever make any progress developing a patch for this enhancement? If yes, even if you didn't get it quite working, it would be useful to push it to Gerrit for review, either with "Test-Parameters: fortestonly" if it is substantially working, or "Test-Parameters: ignore" if it is not even at the stage where it can build. Possibly I could help you finish off the remaining issues, or someone else could take this over at the LUG'24 Hackathon. Please let me know either way.

            ahkumarsmu, did you ever get anything working for this enhancement? I'm just looking at tickets for the next Lustre hackathon and wondering if you have something for this one already.
