Feature request: Different options for backend rights

The permission system currently has two options:

• Administrator
• Normal User

Meaning/Use of terms

Group: is a synonym for team which contains multiple positions

Position: a concrete location or task

Shift: the time slot that is assigned to a position and a volunteer

What would be nice to have

As an administrator I would like to have two more options:

• Volunteer Management
• Team lead

Volunteer Manager

The volunteer management can create all volunteer and assign them to a group.

The manager has the right to move volunteers between the groups and has an overview over positions and shifts.

Team lead

The team lead is assigned to a group and can create positions within the group.

He can not create additional volunteers.

He only see the volunteers assign to his group.
