Open Stack

For future Fuel versions we could/should develop kind of RBAC model for
accessing internal components.
I'm not sure if current nailgun/astute provides any capability like this.
Also plugins often interacts with operating system itself, which is another
area of concern.
IMO we could only rely on plugin certification here.
Not sure if certified plugins are signed actually / and if there is any
possibility to check signatures prior to (or during) plugin installation?
