Improve Job detail view to make it refreshed in real-time instead of reloading

What does this MR do?

Same idea from https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/11797 but for Job details page

• Page does not refresh anymore
• Moves information out of the titlebar into the sidebar
• Structural and small changes to the sidebar to make the sidebar more appropriate for that information
• On mobile viewports, the new issue and retry buttons move to the sidebar
• Update meta-info widget design slightly (remove background and use bigger status icon, similar to mr widget)

Screenshots (if relevant)
