recipe roller doesn't retry or alert on trivial rolls which failed to commit
See e.g. https://codereview.chromium.org/1863543003 . Initial CQ attempt failed. For 7 hours nothing happened. recipe-roller builds were still green.
IMO it'd be better to either retry CQ, or alert in some way that landing the CL failed.
It looks like the build presubmit failed a few times. Should it retry after some time passes in case the build is broken at head?
Alerting makes sense, too.
This is pretty important; this can stall out the roller very easily.
Two options I can think of:
1. The roller looks at previous rolls it tried to do when it's rolling, and pings someone (chrome-troopers ?) if it didn't land.
2. Something else does the same thing out of band of the roller.
