The debian-glue Jenkins jobs times out after 30 minutes regardless of the Gerrit project. operations/debs/contenttranslation/giella-sme is an heavy build that takes hours (ex: https://gerrit.wikimedia.org/r/294430 ).
We need a way to set the timeout differently. Probably passed as a Zuul parameter to be used in the Jenkins job. We would need to keep a sane default.
