Following what is outlined in #10766 refactor the uds-remote-store such that the member variables (state) don't live in the store itself but in the config object. Additionally, the config object includes a new necessary constructor that takes a scheme & authority. Tests are commented out because of linking errors with the current config system. When there is a new config system we can reenable them. Co-authored-by: John Ericson <John.Ericson@Obsidian.Systems>
