Anti-plutocratic mechanism for Curators

[evabeylin]

Consider adding in some kind of anti-plutocratic mechanism to mitigate collusion between curators that are looking to maximize inflation rewards for subgraphs that aren't actually high quality.

Eg. using something like CLR where the total reward distributed is a function of the number of contributors and the total contribution. In this case, instead of the subgraph with the most GRT siganlled/staked earning the most rewards, perhaps its the subgraph that has the most contributors X total value - to reduce the ability for collusion. Can talk more about this in person.
