tests: update testing to not use delay dev
Instead of using delayer device user 'zero' device and let mirror do some real work which takes some time. In case the test machine is too fast - mirror might need to be made bigger to meet needed criteria. Also move all test needed this 'zero' PV trick to the end of test so $dev2 and $dev4 are covered with 'zero' and can take any amount of write without consuming any real space.
