Do we also want a TargetGroup type enum? A target could end up in multiple target groups and at some point we might want to act on all target groups of a specific type?

```
class TargetGroup ... {
  public:
    enum class Type {
      /// A group of spawned processes if we even support attaching to all spawned child processes
      Spawned, 
      /// A group of processes that are related, such as a CPU related to a GPU target
      Related,
    };
```
