Bump this timeout for a couple of reasons. First we've seen the job
timeout at least once in the last month. This seems to be due to gitea
portions of the job running slowly.
Second we're planning some large scale updates to the openstack acls and
a longer timeout should help us get those in in larger batches. We can
consider trimming this back again after these updates are done if gitea
doesn't continue to give us trouble.
