Ensure infra scripts / services use RPC URLs from GCP secrets

[tkporter]

Problem

It seems like following the registry code changes, we no longer use RPC URLs from GCP secrets

Solution

Make sure that we use the private RPCs when running local deploys, kathy, key funder, etc

We should declare a LocalRegistry instance for each environment in infra Then we can use MergedRegistry to combine that with the existing MergedRegistry that @jmrossy migrated infra to if network round trips go the github remote registry are a concern, we can ignore the github registry entirely and just merge the local clone with the environment overrides

I don't totally follow why we'd want separate LocalRegistries for that but RE MergedRegistry I guess this is reason reason number 2 to have it live outside the CLI. I'll migrate it to the Registry repo this week.
