Productionize validator registry phase 2

[shaspitz]

#131 implements the core logic and testing for phase 2 of the validator registry. There are further actions to take before we deploy these contracts to Holesky.

• Determine if DelegationValReg and ReputationValReg should utilize open zeppelins reentrancy guard implementation
• Hash out and test process of upgrading these contracts, this hasn't been tested yet
• Consider separating out contract owner, and account that manages the whitelist. This depends how exactly upgrades will work
• Consider offchain db for keeping track of full list of opted in validators via events
• Automate deploy scripts/process for these L1 contracts, make separate nomad cluster script command for l1 deployments
• Merge feat: validator registry phase 2, core logic #131
• Integrate with go binding generation script
