tests all IEC and SI units related test with a tier pool. as
`target_max_objects` and `target_size_bytes` only apply to tier
pools. so, for the sake of simplicity, tests all of them using
a tier pool.

"version" is not an asok command anymore in the sense that it's served
by registered asock hook. so in this change, we replace "version" with
"sessions", so we can verify that audit channel does not the dispatched
"sessions" command sent from ceph cli.

also, restructure the test as a loop for better readability

…ted_commands()

both "compact" and "scrub" are now cli command, so we cannot issue them
using "tell" anymore.

in cephtool/test.sh, we

ceph fs set cephfs inline_data {1,0}

so the health check fails when the test ends, like

mon.a (mon.0) 3498 : cluster [WRN] Health check failed: 1 filesystem
with deprecated feature inline_data (FS_INLINE_DATA_DEPRECATED)" in
cluster log

so, before we remove the test, we need to whitelist this warning
