API: streamline and make setLogLevel correct

According to the schema, setLogLevel should accept
a log level string ('DEBUG', 'INFO',...). But the code
actually blindly casted the given value to int(), and this suggests
the code actually expected an integer value.

To make things a bit user friendlier and comformant to schema,
change the argument to actually be a log level in string format.

Along the way, this patch streamlines the implementation of
setLogLevel and makes it simpler.
