[FE] Group Cycle Analytics Over Time - (2) Apply a filter
Part of #12078 - please see issue description for problem statement. Breaking down at the request of engineering.
Implementing analytics at an instance level will allow us to move forward with our vision for VSM and have one place for dashboards, which can be used by developers, managers and executives. Many customers have expressed interest in instance level analytics with customizable dashboards allowing users to drill-down in order to uncover actionable insights. (gitlab-ce#48807 (closed))
- Given we will only have group level analytics as an MVC for instance, a user should be able to filter by group, project, subgroup or specific calendar dates using a date picker (http://www.daterangepicker.com). (filtering by author, assignee, milestone, labels will be kept for another iteration)
