iotests: reduce PBKDF iterations when testing LUKS
By default the PBKDF algorithm used with LUKS is tuned based on the number of iterations to produce 1 second of running time. This makes running the I/O test with the LUKS format orders of magnitude slower than with qcow2/raw formats. When creating LUKS images, set the iteration time to a 10ms to reduce the time overhead for LUKS, since security does not matter in I/O tests. Previously a full 'check -luks' would take $ time ./check -luks Passed all 22 tests real 23m9.988s user 21m46.223s sys 0m22.841s Now it takes $ time ./check -luks Passed all 22 tests real 4m39.235s user 3m29.590s sys 0m24.234s Still slow compared to qcow2/raw, but much improved none the less.
