Add Time Tracking Column Totals to Issue board
Description
From https://gitlab.com/gitlab-org/gitlab-ce/issues/27780:
"Time Tracking data, and more importantly estimates, provide important information for the planification.
Issue Board is one of the planification tools we provide within GitLab, and we would benefit from displaying time tracking information in an Issue board."
Proposal
- Show aggregated weight of each column in header
- Show aggregated time estimates of each column in header
- Show aggregated time spent of each column in header
