The lint task in evergreen normally takes around 15 - 20 minutes to complete. Over the last 6 months, the highest runtimes we have seen have been around 35 minutes. About a week ago, however, we saw the lint task get hung and didn't exit until the task timed out. The lint task just uses the default timeouts, so it took over 3 hours before the task actually ended.

Since the lint task is included as part of the commit queue, hangs like this are problematic. They would block the entire queue for a number of hours. To avoid this issue, we should add a more aggressive timeout to the lint task. Something around 40 minutes should be acceptable.

As a server engineer,
I want to lint task to timeout if it runs for too long,
So that I am not waiting on a hung task.
