[LU-10369] running "lfs setstripe -c3 /mnt/lustre/pooldir/newfile" doesn't inherit pool

Testing various scenarios to reproduce ~~LU-10350~~, I found that running the following test did not work as expected, namely that the file created in pooldir/ did not inherit the pool on the parent directory:

pool_add $POOL
pool_add_targets $POOL 0 1 1
mkdir $tdir/$tdir
lfs setstripe -p $POOL $DIR/$tdir
lfs setstripe -c 3 $DIR/$tdir/$tfile-3stripe
lfs getstripe -p $DIR/$tdir/$tfile-3stripe

lfs setstripe -S 3M $DIR/$tdir/$tfile-3M
lfs getstripe -p $DIR/$tdir/$tfile-3M

lfs setstripe -E 16M -S 1M -c 1 -E 32G -S 4M -c 4 $DIR/$tdir/pfl
lfs getstripe -p $DIR/$tdir/$tfile-3M

None of the created files have inherited the pool from the parent directory. Only if a file is created with "touch" does that work. I thought this was fixed in 2.9 with the PFL code, but it doesn't seem to work.

Also, I notice that sanity.sh and test-framework.sh are using a different set of helper functions for creating pools and adding OSTs (pool_add(), pool_add_targets()) than the ost-pools.sh script (create_pool_fail(), add_pool()). It would be good to remove the duplicate functions and only use one set of pool helpers in all tests.
