clustermd_tests: add test case to test switch-recovery against cluster-raid10 

03r10_switch-recovery:
Create new array with 2 active and 1 spare disk, set 1 active disk as 'fail',
it triggers recovery and the spare disk would replace the failure disk, then
stop the array in doing recovery node, the other node would take it over and
continue to complete the recovery.
