Service Team concept

Non trivial service management requires the concept for "service teams". In fact, it is central to a lot of the service management processes:
-------------------------------------------------------------

 New Issues are assigned to a service team first, and then to a team member.
 This allows for a multi-team queue-like workflow: a team member will pick
 the an issue from the unassigned buffer for his team.

 Teams can also be organized in hierarchies.
 This helps to manage common scenarios such as:
 * Level 1, Level 2, Level 3 team workflows.
 * Frontdesk triaging and reassignment to the corresponding specialized team.

 Service Teams reuses the Sales Teams object model.
 This makes it possible for a a Sales Team to also be a Service Team, and
 participate in the resolution of an Issue.
 An example migh be making a quotation for a replacement part, needed for the
 as issues's resolution.
