Summary
PR adds a new reward metric for reward Liquidity Providers for providing liquidity within a specified range.
To make the rewards independent of the liquidity fees accumulated on a market, the transfer implements the concept of "virtual fees". That is, the fees that would have been distributed for a fixed amount of accumulated fees (1 quantum).
This reward metric will require core to compute SLA performance for a number of price ranges and as such a new network parameter is added to restrict the minimum transfer size of transfers to reward pools.
