src: improve logging

Adds new logging handler redirecting messages to the log file
located in the Samba shared directory (applies to live mode
clients, i.e: ogLive)

Parses log level configuration from ogclient.json. See:

{
	"opengnsys": {
		...
                "log": "INFO",
		...
	}
	...
}

Adds --debug option to set root logger level to DEBUG when starting
ogClient. Overrides log level from config file.

In addition:

- Replaces any occurence of print with a corresponding logging function.
- Unsets log level for handlers, use root logger level instead.
- Default level for root logger is INFO.
- Replaces level from response log messages to debug (ogRest)
