Set verbosity in configuration
~~I find it kind of annoying when I launch multiple agents and they all start printing INFO level log messages without me being able to do anything.~~ (https://github.com/opensistemas-hub/osbrain/issues/329)
I suggest we add a configuration parameter / environmental variable to set the level of logging messages that we want to print.
Updated your issue description and created a new issue for the "annoying INFO log messages": https://github.com/opensistemas-hub/osbrain/issues/329
See also https://github.com/opensistemas-hub/osbrain/issues/316. I guess integrating somehow standard's logging or other logging module would ease all of this.
