Aurelien DARRAGON 2513bd257f OPTIM: sink: consider threads' current load when rebalancing applets 
In c454296f0 ("OPTIM: sink: balance applets accross threads"), we already
made sure to balance applets accross threads by picking a random thread
to spawn the new applet.

Also, thanks to the previous commit, we also have the ability to destroy
the applet when a certain amount of messages were processed to help
distribute the load during runtime.

Let's improve that by trying up to 3 different threads in the hope to pick
a non-overloaded one in the best scenario, and the least over loaded one
in the worst case. This should help to better distribute the load over
multiple threads when high loads are expected.

Logic was greatly inspired from thread migration logic used by server
health checks, but it was simpliflied for sink's use case.
