- Discussion topic #1336. - This change migrates away from using `UserDefaults`, instead providing a TOML configuration mechanism for user configurable settings. All existing system property settings keys are supported in the new configuration file. However, users will have to migrate any settings they have configured in the `UserDefaults` into TOML for these settings to take effect. - Breaking changes: * `container system property get` is removed in favor of users directly utilizing `container system property list --format toml | jq<>`. * `container system property set` is removed since the TOML configuration is effectively immutable during the lifetime of the `container` daemon. Uses can edit the TOML they have in their home directory, however no changes will take effect until the daemon is restarted via `container system stop && container system start` * `container system property list --format table` is removed as generating tabular format is non-trivial and the new TOML format is intended to be human readable
