Improve job log rendering performance

See merge request gitlab-org/gitlab-ce!31262

Currently we write out empty CSS classes (`class=""`) every time we
create a new tag. This adds 9 unnecessary bytes per span element. In a
recent trace, I have counted 11950 span elements. So we transported 105
unnecessary kilobytes!

After measuring the impact of the namespace storage on
https://gitlab.com/gitlab-org/gitlab-ce/issues/64092. It was decided
that it's performant enough. So we can freely remove the feature flag
