* Organize logging levels
Log only what we need as ERROR when it's something that we need/want
to take a look that something could be a bug/issue.
There are some ERROR that were replaced by WARNING since they are some
failures but that we don't need to take a look and the message shown
to the user should be enough for them.
* Fix lint issues
* Use the proper exc_info instead of custom formatting
