MLIA-782 Remove --output parameter

* Remove --output parameter from argument parser
* Remove FormattedFilePath class and its presence across the codebase
* Move logging module from cli to core
* The output format is now injected in the execution context and used
  across MLIA
* Depending on the output format, TextReporter and JSONReporter have
  been created and used accordingly.
* The whole output to standard output and/or logfile is driven via the
  logging module: the only case where the print is used is when the
  --json parameter is specified. This is needed becase all output
  (including third party application as well) needs to be disabled
  otherwise it might corrupt the json output in the standard output.
* Debug information is logged into the log file and printed to stdout
  when the output format is plain_text.
* Update E2E test and config to cope with the new mechanism of
  outputting json data to standard output.
