Improving the inline issue and merge request mention status indicator

Issue idea came from: https://gitlab.slack.com/archives/C03MSG8B7/p1492082021843719

Problem

https://gitlab.com/gitlab-org/gitlab-ce/issues/1369 implemented this feature with https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/9462

Now each issue and merge request mention has a status indicator written out at the end. This may be too obtrusive.. notable.

Proposal

This may be a something we have to get accustomed to, but i think its not a bad idea to look into improving the current situation, so its not as obtrusive.

This may also chime in at https://gitlab.com/gitlab-org/gitlab-ce/issues/29585 for showing the full status for example in the tooltip, while we do the always visible part in a truncated version for exampole
