 Description   

Similar to LU-11643, we need to create upgrade test images for conf-sanity test_32a/b/c/d so that we are sure upgrades from those previous versions are working properly.

They should contain files with features added in those releases (e.g. PFL/FLR files, LSOM, Project IDs/Project Quotas, overstriped files, OST pool quotas, ldiskfs large_dir, encrypted directory, CRUSH directory hash type, etc.). They should also be created with multiple MDTs and OSTs to better match normal usage.

The test images themselves should be created as sparse files, to reduce the amount of space used. It might be possible to run "fstrim" on the mounted filesystems to have the kernel punch out holes in the files, but maybe only with newer kernels.

Please also fix LU-10215 (add ldiskfs 2.5 image to RPM) at the same time.
