Devices names and symbolic links

[xuelan]

For destructive raw disk test:
If users use symbolic links in the configuration file, "check for used disks" will fail because find_unused_disks.sh is using device name. Can we do some optimization or user should always use device names?

So far I have not seen a customer using symbolic links for devices.
Best is to go with device names.

@xuelan I thought about this, I would keep the behaviour for current types, but introduce a new type DESTROY_UNSAFE which is not performing the find unused disk test
