This PR implements the rewards mechanism for variable stake per node.
Nodes still receive higher return (configurable) for the base stake (minimum nodes price), but now any extra stake can earn rewards as well.
The rewards formula for any excess stake is not linear but asymptotic to a configurable maximum, and also the starting gradient is configurable.
Backwards compatibility was implemented through a rewards creator proxy that delegates the functionality to the correct rewards model depending on the activation epoch.
