ui: the host detailed view should include tasks that were delegated to it

[dmsimard]

What is the issue ?

Sometimes hosts are recorded without apparent results:

This is because the host did not run any tasks directly on it's own but was rather delegated tasks from another host.

What should be happening ?

We have access to these results via the API (/api/v1/results?delegated_to=<id>) so we should be able to include these when we recover the results for the host:

ara/ara/ui/views.py

Lines 222 to 223 in e5ec563

	result_queryset = models.Result.objects.filter(host=host_serializer.data["id"]).order_by(order).all()
	result_filter = filters.ResultFilter(request.GET, queryset=result_queryset)
