Reduce gas cost of deploying a Graph Curation Token by using MinimalProxy

[abarmat]

The gas cost of deploying the subgraph token can be greatly optimized by deploying a minimal proxy each time, sharing the same bytecode.

@abarmat I think we can close this as it was implemented in #505 right? Or are there further optimizations you think can be made?

@tmigone exactly this is already implemented, I'll close it
