Implement a date picker for cycle analytics
Problem to solve
Currently users cannot select a specific date for customizable cycle analytics, which means that they cannot drill down in productivity during a specific sprint since we only provide last 7, 30 days, etc as periods.
EMs, PMs, Tech leadership
I would recommend adding a date picker to cycle analytics page, where currently the custom ranges are, similar to the spec in productivity analytics.
With customizable stages, we will be able to scope the calculation between a date range. TODO: sync with FE about the param naming.
Permissions and Security
Same permissioning as on the overall page
What does success look like, and how can we measure that?
A user should be able to select any period for which they have data and load it within  seconds
