This MR added three small functionalities:
the logging level is now configurable by using STORK_LOG_LEVEL. If not specified, or specified with garbage, the default value of INFO is used.(see !548 (closed)).
- the BIND9 detection is now a bit more verbose on info. It's much more verbose if DEBUG log level is enabled.
- It is possible to explicitly say the BIND 9 config file location using STORK_BIND9_CONFIG variable.
