feat: Rewards v2

[0xrajath]

Motivation

As part of the Rewards v2 release, we need to support the following features in middleware:

1. Performance-based Rewards submission by AVSs.
2. Set Claimer incase any funds are refunded to the AVS.

Depends on Layr-Labs/eigenlayer-contracts#837

Modifications

• Bumped up eigenlayer-contracts dependency to match Rewards v2.
• Refactoring existing commission terminology to split, and global terminology to default for RewardsCoordinator.
• ServiceManagerBase, ECDSAServiceManagerBase and IServiceManager :
  • createAVSPerformanceRewardsSubmission function for AVS to submit performance-based rewards.
  • setClaimerFor function for AVS to assign claimer on its behalf incase of funds being refunded to the AVS.
• Updated RewardsCoordinatorMock in test to implement new functions.
• Updated Tests

Result

Rewards v2 release.
