* Add support for IPMIv2 Kg Key in device settings
Some devices require that the Kg key be specified. An example would be a server of mine, a Cisco C220 M3.
Otherwise, it would error out with `Error: Unable to establish IPMI v2 / RMCP+ session`.
With verbose output enabled, the connection attempt would stop at `RAKP 4 message has invalid integrity check value`.
* Add Kg key support in Poller
* Sanitize Kg key from debug output
* Added Kg key support for discovery process
And it seems to work like a charm. New fields, such as fan tachometers, were added in automatically.
* Applying StyleCI changes
