    * op-batcher op-proposer op-service: Introduce op-service
    
    op-service is a utilities library that automates much of the boilerplate setup we've been duplicating across different daemons. This PR adds the following to op-batcher:
    
    - Common setup utilities for logging, metrics, pprof, and RPC.
    - For each of the above functions, a set of CLI flags and configs that can be used to parse + validate CLI configuration for that module.
    - A base RPC server that implementers can extend.
    - HTTP metrics utilities.
    
    * update dockerfiles
    
    * code review updates
    
    * op-service: temporary replace, until op-service go module is canonical and can be resolved
