The setup of the logs and the parsing of the config file are closely related. The former need info from the later to be created, and needs to be setup only once
per pisa instance. In the same way, the later need to only be loaded and validated once per pisa intance and contains info to setup the logs.
Intead of setting up the logs in init and loading the config file in pisad, now both are dealt with in __init__
Splits the logging in two loggers (console and file) so the logs can be formatted separately.
A more complete console logging is required though. Right now it only should the message, but it would be nice to include also the parametters in a human-redable and friendly way.
Fixing it using a single Logger will also be nice, but not worth spending too much on.
