Description

We currently don't have node name in the NewDeps call. To add it we can keep tacking on new configuration values or we can add new values to the already existing config struct that is built in the builder.

There was a mini refactor required because the cfg is also used as an interface to instantiate the metricsClient. To reduce blast radius of a very large refactor I moved the instantiation of the metricsClient out of the sink initialization and then passed in the metricClient to the sink instead of passing the cfg in as an interface which stops us from using any of the values stored in the config.

I still think we should refactor the function for NewMetricsClient to not take an interface but for now I think this is an acceptable crawl step. We should work making this code a lot simpler as we are doing quite a bit with the "config" and treating it very much not as just config.
