It is not possible to get the default logger object in Caporal 2

Is your feature request related to a problem? Please describe.
Winston, unlike other logging libraries such as bunyan, lacks a .trace() method. This means that if I use a Winston with libraries that expect loggers to have .trace() methods, those libraries will fail. One simple work around is to simply add a .trace() function to the logger object that is equivalent to Winston's .silly() or .debug(). In Caproal, 1.X the entire problem could be resolved by adding the following 3 lines of code to your main entry file:

// Make winston logger bunyan compatible
const logger = program.logger();
logger.trace = logger.debug;

The above code gets the default logger object and then wires in the missing level. Unfortunately, no similar equivalent is possible in Caporal v 2.X as there is only a logger setter with no corresponding getter.

Describe the solution you'd like
Either

• A: In Caproal v2, running program.logger() should return the current logger used by the program and not set the logger to undefined.
  or
• B: program has a new property logger which is the logger object used by the program.

Describe alternatives you've considered
Monkey patch the line logger.trace = logger.debug; to the beginning of every action function.
