Interoperability with LNet Health feature

Tests cases listed in this section are intended to verify that UDSP and LNet Health features work properly when both are enabled. The expected behaviour is that UDSP decisions come second to the health-based decisions, such that, for example, given healthier alternatives, NID with a lower health score won't be chosen even if it is preferred according to a UDSP rule. More detail on how to simulate events that affect the health score can be found here: LNet Health Test Plan [3].
