Spike: Update the config watcher for log trigger limits

[ferglor]

TBD:

• What data types should we be working with in the go code?
• Is cfgWatcher.chain.Config().EVM().OCR2().Automation() the correct path for these values?
• How does an on chain config map to the config watcher?

I see that you haven't updated any README files. Would it make sense to do so?
