Display indication of tests being timed out

[donny-wong]

Description

When tests times out, there are no indication on MarkUs side to show this. It simply leaves the test results as blank. We would like to have some indication to show the end user the test timed out. Also, we need to log the time out in the autotester worker logs, as it currently does not.

Some examples where this time out can happen:

1. There are tests where they are CPU intensive, where multiple tests running parallel will compete for CPU resources, and they some how just hangs until the time out is reached.
2. Tests that use the AI-Server, where the AI-Server is busy with other requests, and so the tests will need to wait and may hit their time out.
