UMIP 112 -Add uDAO_KPI_UMA as a supported price identifier

The DVM should support requests for** UMA protocol integrations.

Key Performance Indicator(KPI) options are synthetic tokens that redeem to protocol tokens with the redemption value determined by performance against that indicator. One example of a KPI metric is Integrations. Integrations serve to measure the activity of the protocol rather than assigning all of the value to the dollar amount generated by the protocol, as previously seen in UMA’s TVL KPI option.

This UMIP enables the DVM to support price requests based on the number of qualifying integrations that occured during a specified timeline. This UMIP relies on the use of ancillary data, and will include a section on that below.

A synthetic option is minted against a base collateral, in this case UMA.
