With the 2.57 microversion, we: * Deprecate the --file option from the nova boot and nova rebuild CLIs and API bindings. * Add --user-data and --user-data-unset to the nova rebuild CLI and API bindings. * Deprecate the maxPersonality and maxPersonalitySize fields from the nova limits and nova absolute-limits CLIs and API bindings. * Deprecate injected_files, injected_file_content_bytes, and injected_file_path_bytes from the nova quota-show, nova quota-update, nova quota-defaults, nova quota-class-show, and nova quota-class-update CLIs and API bindings.
