[QA] reducing history of browser test jobs

[Antoine Musso]

Hello,

We run the browser tests twice per day and keep the history of builds ad
vitam.

A side effect is that the Jenkins view for browser tests takes a couple
minutes to load on first hit.  That is because Jenkins lamely load the
while history of all jobs to generate the [dashboard].

S Page filled [bug70671] about that slowdown.  It could be improved by
dropping browser tests history after a set amount of time, at the
expense of losing the long term trend.


I would propose to only keep 15 days of history (or 30 builds). That can
be done in Jenkins Job Builder using the 'logrotate' publisher.
