Avoid BindException after restart

[lovebing]

Sometimes server start failed after restart, like:
#687
#698
Some developers don't know how to solve this problem, so I think this is a good idea to set the default value of SocketConfig.reuseAddress to true. It can avoid the BindException.

LGTM

You can change the field through the available public method in SocketConfig (See Wiki).

Configuration configuration = new Configuration();
SocketConfig socketConfig = configuration.getSocketConfig();
socketConfig.setReuseAddress(true);

That's all you need
