Default fence_scsi_test: add option for strict verification

Add new option --strict (-s) that will enable strict verification that
registrations are created on all paths. Previously this was the
default behavior. Strict verification will compare the number of times
the registration key exists on a device and the number of paths. This
is useful when testing multipath configurations. If this option is not
specified, the verification will simply check to make sure the
registration keys exist on the device.
