Missing informartion about CyberArk Key Storage Plugin

[Lverdile]

Describe the Bug

There isn't a well-described explanation on how to configure the CyberArk plugin to get it working.
There's a lot of confusion between the customers on how to properly set the parameters, and which ones are needed and how to configure it

Pull requests welcome :)
We don't have access to a CyberArk instance anymore. We can try getting help from Cyberark, but if anyone else would like to jump in and provide content that would be most helpful.
