Rewards Initiator

The RewardsInitiator handles reward accounting and distribution updates for the StakingPool. It periodically initiates reward updates by calling the StakingPool to trigger a rebase followed by the SDLPoolCCIPControllerPrimary to distribute rewards to all secondary chains. It will also trigger an emergency rebase in the case of a slashing event within the StakingPool.
