Description Aakash Jain 2023-09-18 14:24:32 PDT 
Similar to https://bugs.webkit.org/show_bug.cgi?id=261614, webdriver-test step should also fail builds that exceed a predefined threshold of log lines. This can cause buildbot to grind to a halt as it cannot handle the memory / database load.

(This is a subtask of https://bugs.webkit.org/show_bug.cgi?id=249054)

One example was on 2022-12-09 when the buildbot server was extremely slow and returning 502. The cause was huge logging, 
e.g.: over 5 million log lines in webdriver-test step in https://build.webkit.org/#/builders/730/builds/13
