It can also be annoying to have to let a simple boot test run for a full minute. This commit therefore permits an "s" suffix to specify seconds, "m" to specify minutes (which remains the default), "h" suffix to specify hours, and "d" to specify days. With this change, "--duration 5" still specifies that each scenario run for five minutes, but "--duration 30s" runs for only 30 seconds, "--duration 8h" runs for eight hours, and "--duration 2d" runs for two days.
