Have Konstraint generate GateKeeper's expected v1 Syntax

[EmekaNnaji]

Hello,

As of GateKeeper v3.19.0, Gatekeeper now offers v1 syntax support. It looks like right now that feature is enable via opt-in in your constraint template. Does Konstraint have any means to generate Constraint Templates in the v1 format that GateKeeper expects?
