consequently, several classes which were both in lb-classic and slf4j-api 
were removed (from classic).

- getLogger method was removed from LoggerContextAware (we no longer need loggers
 to report internal errors as we use Status instead)
  DateConverter and ClassicConverter were modified as a consequence to use Status instead
 of logger
