Tests should calucalte expected array_size accordingly to raid level. Also
tests should take care about runding to neares MB introduced from b53bfba6
"imsm: use rounded size for metadata initialization".
Expect proper size in tests. Simplify 09imsm-overlap test by creating array
with size which has not been rounded. Main purpose of this test is checking
something else.

Grow feature for IMSM metadata is currently fully supported and tested.
Reshape operation is not in experimental state anymore, so usage of this
flag is unnecessary.
Do not require MDADM_EXPERIMENTAL flag and remove obsolete information
from manual.

raid0->raid10 transition needs at least 2 spare devices.
After level changing to raid10 recovery is triggered on
failed (missing) disks. At the end of recovery process
we have fully operational (not degraded) raid10 array.
Initialy there was possibility to migrate raid0->raid10
without recovery triggering (it results degraded raid10).
Now it is not possible.
This patch adapt tests to new mdadm's behavior.

When imsm container is created it have different blocks number
in /proc/mdstat depending on containing array raid level (raid0/raid5).
raid5 case:
md127 : inactive sdd[3](S) sde[2](S) sdc[1](S) sdb[0](S)
2884 blocks super external:imsm
raid0 case:
md127 : inactive sdd[3](S) sde[2](S) sdc[1](S) sdb[0](S)
836 blocks super external:imsm
Due to this, it cannot be compared to one value for both cases.
Test imsm container existence before unit test run only.

Patch provides set of tests for On-line Capacity Expansion,
takeover, migrations operations for imsm metadata type.
Tests are grouped by operation type:
12 - On-line Capacity Expansion on one volume
13 - On-line Capacity Expansion on two volumes
14 - Negative tests for takeover, migrations
15 - Chunk size migrations
16 - raid0 -> raid5, raid5 -> raid0 migrations
18 - takeover operations
To run particular test group, following command should be executed:
(from mdadm's source code root directory)
./test <group number>
Example:
To run On-line Capacity Expansion on one volume tests:
./test 12
Tests execution results:
- In case of test pass, "succeeded" word is printed on console
- If test is failed, "FAILED" word is printed on console
and logs are stored in <mdadm-root-dir>/tests/log/ directory
