Global Team Selection object

[vbakke]

Now that we have team selection multiple places, it would be good to lift the selected team to a global state in SessionStorage.

• No teams selected should be the same as all teams selected
• Selecting a Group must select the corresponding Teams
• Selecting Teams that match a Group, should highlight/select that given Group (like todays chips in Heatmap. see below*)
• teams selected on one page should de the default selection when opening another page that has a team select feature

This applies to:

• the Heatmap page
  • The chips next to the heatmap
  • View Evidence - Only show evidence for teams selected
  • Add Evidence - Use selected Teams as default when opening popup
• the Report page
  • the Report page itself
  • the bottom of the Report Configurator

* To test re-select Group, try the following:

1. Group 'Customer' then Team A and Team B gets selected.
2. Deselect Team A, and the Group looses the 'Customer' state. (Works well today).
3. Re-select Team A, the Group should now re-enter the 'Customer' state

If we can put this logic in the central component, it should be easy to implement every place that the user can select Team/Group.

Parts of this issue is coupled with issue #588.
