Merge branch 'clickable-labels' into 'master'

Clickable labels

When I open issue with label `Ready for Merge` I usually want to see more issues with this label. I should visit project issues page and click on such label to see issues filtered. With this MR labels are clickable so you can get in one click from Issue show page to all issues with same labels

See merge request !1085
