Add distribution (multi-processor support)

[alirezamika]

One of the strengths of evolution strategy algorithm is its linear scalability.
Thus it would be great to have this implemented in Evostra.

@alirezamika I am interested in working on this. How do I start?

[alirezamika]

I haven't started on working on this yet. We can go with the master-slave approach. Slaves should be able communicate with master over network and solve their own task using the given data from master.

Any progress on this?

I have been implementing my own version of ES using keras weights, inspired by https://blog.openai.com/evolution-strategies/ . I am currently working on running parallel on cpu. I will let you know if I have progress. You can follow the work here: https://github.com/LinuxIsCool/756project

@hipoglucido @LinuxIsCool I've implemented multiprocessing support which is working fine.
Next step is to add distribution support over network.
