Only require the activeGate token scope if activeGates are used

[0sewa0]

The token checking logic only checked if the feature-flag is present or not, and in 0.9 it became default, so it always required it, even though you may not even want to deploy activeGates

How can this be tested?

Use a token without the activeGateTokenManagement.create scope
Deploy a dynakube without ActiveGates => should work
Deploy a dynakube with ActiveGates => should complain about the tokens
