Merge branch 'timetracking-1.1' into 'master'

Implement Timetracking v1.1


- [x] Break issuable_time_tracking component into smaller components and bundle them
- [x]  Improve the help state UX to look like this: https://gitlab.com/gitlab-org/gitlab-ee/issues/985#note_16056031
- [x] Create helpers for props existence checking  https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/870#note_18534273
- [x] Standardize on camelCase where possible, improve naming with computed values
- [x] Be clear about using human values from the server vs client 
- [x] Address the accessibility impact of only displaying the remaining time in a tooltip and the percentage of time spent in a colored meter.
- [x] Fix help 'Learn more' URL
- [x] Remove polling until the rest of the sidebar can be synced properly
