move cfg to loggers + refactor + log fn wrappers

Browse source 
1. Instead of maintaining a global config, each specialized logger
now stores its config.
2. Refactored logInterface to elektronLogger.
3. Refactored loggerImpl to baseElektronLogger to be consistent with
the rest of the code base.
4. Wrapped elektronLogger#Log(...) and elektronLogf(...) so that we
do not have to use the instance of elektronLogger everytime we want
to log. Instead, we just do logging.Log(...) or logging.Logf(...).
5. Wrapped elektronLogger#WithFields(...) and
elektronLogger#WithField(...).
6. Refactored codebase to adhere to the changes.
