[rules-users] Parallelization in Planner

[Geoffrey De Smet]

Hi Nurlan,

This feature isn't implemented yet, but will be resolved together with 
the issue for multi-threading the Solver:
   https://issues.jboss.org/browse/JBRULES-681

I have a working design in my head and on paper here for the basic.
Basically, a Move will be parallelized over CPU's and JVM's.
The critical thing that made this hard is not breaking incremental score 
calculation (delta's),
which would make it slower than single-threaded, not faster, but I 've 
found a way to do that.

I 'll look into jgroups to do the JVM communication by default, but I 
'll probably make that pluggable.

Note: better optimizations algorithms usually beat adding more CPU's - 
but doing both is even better of course :)
