For embeded reshaping operation require higher driver version.
(otherwise we get:
Converting vg/LV1 from raid6 (same as raid6_zr) is directly possible to the following layouts:
raid6_nc
raid6_nr
raid6_la_6
raid6_ls_6
raid6_ra_6
raid6_rs_6
raid6_n_6
lvmpolld ATM is not desingned to preserve interval checking
in the same way the 'lvconvert' tool is doing - so the passed
'-i 40' is not respected and lvmpolld autonomously checks
state of conversion and updates lvm2 metadata and dm tables
when needed.
So skip portion of test that relayed on this and preserve this logic
only for command line invocation and forking of polling process
where the interval of checking is under full control.
Add a little wait loop - since lvconvert started background process
and we need to wait till this bg task initiate its work -
adding ~1s loop should give reasonable enough time to start mirroring.
Since the test is currently directly working with live directory,
which can be getting updates from system's udev - add wait
for settling so removal of all known PVs happens after that.
But still this has major influce on behavior of running system,
so the test should never be executed on a user used box.
Commit 989626926c98cd00f0236c4fcac883107d76899d
introduced 2 new tests
lvconvert-raid-takeover-linear_to_raid4.sh and
lvconvert-raid-takeover-raid4_to_linear.sh
which involve raid reshaping.
Bump the checked dm-raid target version to 1.14.0
which has reshape kernel fixes to avoid test suite
runs to hang.
Bump target version to 1.14.0 which contains fixes
for reshape deadlock/corruption to allow tests to
run once the respective fixes show up in kernels.
Remove now superfluous multi-core checks.

Allow "lvconvert --type linear RaidLV" on a raid4 LV
providing convenient interim steps to convert to linear.
Add respective new test
lvconvert-raid-takeover-raid4_to_linear.sh
and
lvconvert-raid-takeover-linear_to_raid4.sh
for linear to raid4 once on it.
When converting from striped/raid0/raid0_meta
to raid6 with > 2 stripes, allow possible
direct conversion (to raid6_n_6).
In case of 2 stripes, first convert to raid5_n to restripe
to at least 3 data stripes (the raid6 minimum in lvm2) in
a second conversion before finally converting to raid6_n_6.
As before, raid6_n_6 then can be converted
to any other raid6 layout.
Enhance lvconvert-raid-takeover.sh to test the
2 stripes conversions to raid6.

"lvconvert --type linear RaidLV" on striped and raid4/5/6/10
have to provide the convenient interim layouts. Fix involves
a cleanup to the convenience type function.
As a result of testing, add missing sync waits to
lvconvert-raid-reshape-linear_to_raid6-single-type.sh.

Conversion to striped from raid0/raid0_meta is directly possible.
Fix a regression setting superfluous interim raid5_n conversion type
introduced by commit bd7cdd0b09ba123b064937fddde08daacbed7dab.
Add new test script lvconvert-raid0-striped.sh.
