Add zesDeviceReset ULTs.

Browse Source 
This patch adds two ULTs.

Verify that an IN USE error is returned if the device is open by another
process.

Verify that reset succeeds if device is not in use.

Verify that reset with force succeeds if device is in use.

Verify that reset without force succeeds if device is opened during
reset, and process is killed.

Verify that reset with force fails with device in use
if device is opened during reset, and process will not die
