There are three tests that only differ in delays (and a few other minor details line whitespace formatting and number of retries). Let's unify those so maintaining this code will be easier. This also implicitly increases the number of retries from 3 to 10 for the non-default --interval tests. Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>
