Filed https://github.com/tarantool/test-run/issues/214 , where I
proposed to add a mechanism to elide all past logs for grep_log() and
wait_log().

Let's consider vinyl/compact.test.lua way for a while:

 | -- <prepare>
 | require('log').info(string.rep(" ", 1024))
 | -- <commands that either produce some logs or don't>
 | test_run:wait_log(<...>, <...>, 400) == nil

(Don't miss [1]. Don't sure whether it is still actual after [2].
Please, either check it strongly or keep being on the safe side with
1000/400 magic numbers.)

This way is less intruisive than modifying another test.

CCed Sergey as author of the test case.
