Remove a team
Description
When I'm viewing a team's details, I'd like to be able to remove the team.
Proposal
For users with owner permissions for the group:
- Removing a team option should only be presented with adequate permissions.
- Removing a team should require confirmation. We should inform the user of the number of members still remaining in the team.
- If a team is removed, all members of that team should no longer be associated with that team and the team should no longer be presented in the team list.
