system_reset_bootable picks random times to sleep for between
reboot iterations.
Prior to this patch it used integers, and so always waited for
whole numbers of seconds.  This causes a problem where there's
a sub-second failure window during which a reboot would fail.
Depending on the system, qemu version and luck, the window could
completely miss the failure (reliably), and a small change
(such as a slightly different qemu build or host system) could
move the failure window within a second-boundary that would be caught.
This results in blaming the change rather than the original
fault.

Solve this by moving to random fractional values, at millisecond
resolution; there's probably more than a ms slop in the system
anyway.

1. Modify the repeat time from 300 to 100 about with_repetition test.
   Repeat 300 times takes too long time.
2. Modify the repeat time from 3 to 1 about not repetition test.
   Repeat hotplug and unplug can be covered by with_repetition test.
3. Limited the with_shutdown.after_plug only with_plug,
   When test without_plug, this case is no needed.
