When the drive failure occurs, the IDM lock manager and lvmlockd should handle this case properly. E.g. when the IDM lock manager detects the lease renewal failure caused by I/O errors, it should invoke the kill path which is predefined by lvmlockd, so that the kill path program (like lvmlockctl) can send requests to lvmlockd to stop and drop lock for the relevant VG/LVs. To verify the failure handling flow, this patch introduces an idm failure injection program, it can input the "percentage" for drive failures so that can emulate different failure cases.
