docker_container: improving idempotency (#44808)

* Only handle cpu_shares, volume_driver, auto_remove as in _host_config().

* Don't compare log_options (resp restart_retries) if log_driver (resp restart_policy) is not specified.

* Warn that log_options (resp restart_retries) is ignored if log_driver (resp restart_policy) is not specified.
