Generic price data provider running. Looking to depeg next

DO NOT PULL (in progress)

This is a running version of a generic controller, meaning the stake price is generic. However, the dpeg event is still anchored to price data, and I am working on generalizing that with a generic condition interface.

Interesting files: All in Controllers for now:
Controllers

• ControllerGenericV2.sol - A controller with some work in progress around moving price out
• ChainlinkPriceProvider.sol & IPriceProvider.sol - A first pass at a provider which provides on demand price data when requested
• PriceBasedDepegCondition.sol_inprogress & IDepegCondition.sol - (in progress) a Generic Depeg condition trigger, that rests on top of any IPriceProvider.
• EndToEndV2GenericTest.t.sol - Test case, which sets up the ControllerGenericV2 and tests it.

As I am still onboarding, I chose to create a new controller and independent EndToEndV2GenericTest, as to not disrupt any other class.
