As a CDAP user, I want to be able to know if a pipeline has concurrent runs that are running (aka "active runs"). I also want to be able to navigate to the details page of an active run.
When there is more than 1 active run, the number of total active runs is surfaced next to the status of the run (run x of y).
The user selects that link to open a popover listing all the concurrent runs
- A maximum of 5 runs in listed, if there are more than 5 active runs, a scroll bar is displayed
- The run currently viewed is highlighted
- The user can navigate to another active run by clicking on one of the listed run (on hover, the background of the row changes to Grey_08 #f5f5f5)
