Wow this is great, why have I not thought about it beforehand?

We can reduce the log size if we truncate everything before 
ERRORS/FAILURES output of pytest run (we leave the log as it is if the 
fail occurs before this stage), that should shave off considerable 
amount of cruft from the paste unless somebody sends a PR that breaks 
all out tests :D.

I would also paste the output to "freeipa" or even better 
"freeipa-travis" namespace and only send it if the job fails.

IMHO yes, but TTL is hard to determine, since the author of the PR may 
not be present to review the results immediately (because he is on PTO 
etc.). I think we should set TTL to something like 1 week and as a 
fallback keep tailing the CI results log.

Fraser, are you OK with waiting with this effort until we push 
https://github.com/freeipa/freeipa/pull/361 ?. I will just do some more 
adjustments there (like result log trimming) and it should be pushed ASAP.
