Merge branch 'dz-cleanup-counters' into 'master'
Remove counters from Pipeline navigation * counters are heavy from UI perspective * duplicates information from tabs below * shows 0 for less active projects. Jumps from 0 to N constantly. I think we should render counters only when necessary and only for filters ( tabs on white bg ). Exception: issues, merge requests in top navigation as status of project popularity and action required from maintainers cc @grzesiek @ayufan @jschatz1 See merge request !4617
