FIX: removed pinging of the CS when refreshing

I was tempting to do the exact same earlier today and then realized it is not a good idea, because a completely overwhelmed slave could still call the method from the master. So I tried hotfixing it to reduce the timeout to 2s.

I do not see any added value in attempting this ping, anyway in most cases the slave will not be added to the list (because it would be there already)

I am not sure I understand what you mean. The list of slave is cleaned every 10 minutes (by default).

Ah, I had forgotten about that. What is the reason for such a frequent cleaning?

10 minutes is a long time to have a dead server in the list
