Multiple things could slowdown drastically TcpSyslogMessageSender

TcpSyslogMessageSender has three things that need to be change in order for that class to be more reliable regarding performance

1. Connection timeout should be configurable and have a default value of 5ms (or even less)
2. Inner retry mechanism should be remove or be configurable
3. sendMessage should not be a synchronize method (actually one thread at a time can sent a log and could lead to huge slowdown when there is high volume of event being log)
- my recommendation is to start using non-blocking socket and remove the synchronization in order to avoid any performance issue
