vgrename does not support -S|--select, so do not provide a hint about
using it. Instead, provide a hint about using VG uuid directly.

WARNING: VG name vg1 is used by VGs DXjcSK-gWfu-5gLh-9Kbg-sG49-dtRr-GqXzGL and MVMfyM-sjOa-M2xV-AT4Y-JddR-h4SP-UO5Ttk.
Fix duplicate VG names with vgrename uuid, a device filter, or system IDs.

In case of e.g. 3 PVs, creating or extending a RaidLV causes SubLV
collocation thus putting segments of diffent rimage (and potentially
larger rmeta) SubLVs onto the same PV. For redundant RaidLVs this'll
compromise redundancy. Fix by detecting such bogus allocation on
lvcreate/lvextend and reject the request.
Check for running (possibly leftover) lvmdbusd running in the
system - as this daemon may interfere with this test as in this
case both be operating on same 'live' data in /run/lvm.
Make test faster by agregating sets of operation to work on a single
created filesystem yet checking all the variants of extension and reduction.
Split 'xfs' part into separate test and convert it for use of the
minimal size 300M nowdays required by mkfs.xfs.
lvreduce uses _lvseg_get_stripes() which was unable to get raid stripe
info with an integrity layer present. This caused lvreduce on a
raid+integrity LV to fail prematurely when checking stripe parameters.
An unhelpful error message about stripe size would be printed.
When lvmcache info is dropped because it's an md component,
then the lvmcache vginfo can also be dropped, but the list
iterator was still using the list head in vginfo, so break
from the loop earlier to avoid it.
Previous commit cause the pvmove could actually be started in unexpected
order - so make sure, we are not starting new pvmove in same VG until
the previous one is started.
Keep backups within test_dir instead of dev_dir (so it doesn't
leak large files there if the tests are run over real /dev dir).
Move restoring of dm_mirror throttling before test_dir is removed.
Not quite sure if this helps anything, some of testing
machines can't reliably remove scsi_debug, reporting
they are in use - but it's not easily reproducible...
aux wait_pvmove_lv_ready() now handles multiple pvmove LVs
at one go - which allows a bit fast checking - although
at some point we may need to switch to use delayed devs
since mirror throttling seems to be no longer working well,
as CPU are getting so fast, that most of data are already
pvmoved before throttling has any chance to do something...
When 'brd' device can be removed (is unused AKA not opened),
remove such device and use again for testing.
Let's assume user has no unused brd device left in the system.
When the 'tests' sometimes fail to cleanup devices, with this
change futher cleanup from some next test may evenually release
brd device and make it available for testing.
There is no easy way to detect, whether device supports zeroing,
and kernel also zeroes device when it's not directly supported,
but with extra message:
operation not supported error, dev X, sector Y op 0x9:(WRITE_ZEROES)...
So to avoid generating such message with every 'lvcreate', use for
zeroing of upto 8K just standard write of zeroed page.
(maybe we can go with even larger sizes).
