[infra] feature request: inspect new luci summaries for infra failures (No Android devices detected) #166996
Description
Reduce the number of "flakey" or false-positive failure reports.
We now get summaries for luci jobs. We could summarize these to see if some of the most common infra failures are present (e.g. no phones).
