DTLS client - improve the example

- Remove redundant pingTimer.start() call (timer is not a single
shot timer and already started before this point in code).
- Use connected UDP sockets to show that it can work with QDtls.
- Replace (translated) string concatenations with formatted strings
  and 'arg' where needed.
