Requirements

1. Users should see the values.yml values associated with opencost helm install.
2. Users should have a way to edit this key value pair attached to the deployed values and apply the changes. This will trigger updates the valyes.yml values within k8s and restart the pods so new values are picked up
3. Users should also have a way to add more key value pairs in this edit window.
4. All of these configurations should be part of a "Settings" left navigation
