Enable tests for OLCE, takeover, migrations for imsm metadata

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
