Create a function to stabilize test that are flaky due to page features that are not relevant for the test

[occupant23]

I noticed, that the code like this

        try
        {
            $("#onetrust-accept-btn-handler").shouldBe(visible);
        }
        catch (ElementNotFound e)
        {
            overlayIsVisible = false;
        }

is/can be used in multiple projects, e.g. I built a custom method like this for a customer project. Wouldn't it be a good idea to extend SelenideAddons with methods to wait until or while some condition, without any exception throwing but just returning a boolean value as information whether the condition was fulfilled?
