Configure the Sprint Health Gadget colors based on the issue status

Today, the Sprint Health Gadget colors are based on the status categories of the board:

1. Blue (To Do) - Consider the status in the first column of the board
2. Yellow (In Progress) - Consider all the status in the columns between the first and the last column of the board
3. Green (Done) - Consider the status in the last column of the board

That being said, if you have multiple statuses in the "In progress" category, all the estimation is displayed together with the same column. 

Please, allow the possibility to add separate colors for each status.
