Standard interface for an AMM yield integration contract compatible with the Kernel.
An AMMIntegration support the configuration of multiple pools at the system integration level.
An integration implementing IAMMIntegration MUST NOT use poolID 0. The system recognizes an integration as an IAMMIntegration when the poolID > 0.
