[ct_telnet] Improve debug printouts and logging
ct_telnet_own_server_SUITE:large_string sometimes fail in the last attempt - where get_data is used to fetch smaller chunks - probably because one get_data message towards ct_telnet_client returns without having received any new data. This commit adds timestamps to debug printouts and improves the logging.
