Abstract the configuration storage mechanism to allow using custom configurations, such as in-memory setups, when using the tool as a library. This aligns the configuration architecture with the session cache abstraction. - Define ConfigInterface protocol and InMemoryConfig class - Make CacheFile, InMemoryCache, ConfigFile, and InMemoryConfig explicitly inherit their interfaces - Update MdrsService and MdrsClient to accept customizable config_class and config instances - Add validation to check remote parameter consistency in create_connection - Remove unused imports across command files
