trx_toolkit: introduce logging configuration arguments

Before this change, it was impossible to configure logging
parameters from command line, such as log level and format.

This change introduces the following optional arguments:

  --log-level - logging level for stderr (by default, DEBUG);
  --log-format - logging message format for stderr;

  --log-file-name - enable logging to a given file;
  --log-file-level - logging level for file (by default, DEBUG);
  --log-file-format - logging message format for file;

which are defined in a new class called ApplicationBase, so
all existing applications should inherit them now.
