MySQL Master-Slave-Slave replication in Docker

@ingvar-goryainov can we make the replica count configurable or as user input with a default of 1 replica . @vbabak what do you suggest?

@sarbesh configurable amount of replicas is a good point.

Actually I have thought that "Master-Slave-Slave" was about chained replication. That's a little bit different setup comparing to multiple replicas. I would like to share some example which I believe could be also good for learning replication in the issue https://github.com/vbabak/docker-mysql-master-slave/issues/10
