Code review comment for lp://staging/~psivaa/ubuntu-test-cases/per-test-timeout-autopilot-for-rtm

I think we had hanging issues in rtm a little while ago and it's a matter of time before we see another one. If by chance we see that then it will be on us to rerun the missed tests due to that hang and that process is messy because we need to cherry pick the apps but the hanging one to have the rest of the results.

Also, this ppa injection is only for the rtm though, so this is not changing anything for non-rtm runs.
