Description:
As mentioned in the linked issue, the
least-weightedallocation strategy is at the moment not capably of scaling out. Shortly explained, after the targets are distributed across the initial set of collector instances, the newly added collector instance will not be assigned any targets.This added test ensures that the current capability is covered. In case it will be decided in the future to change the implementation in order to achieve scaling capability, this test will fail and will thereby signal for a new test to be created.

Testing:
The test
allocation/TestNoAssignmentToNewCollectoris added.Documentation:
The test assures that the newly added collectors are not assigned any targets after a successful target distribution across the initially detected collectors.
