--subdomains and --skip-email not getting cover for multisite-install command

[1naveengiri]

After checking this code

.....
....
if ( isset( $assoc_args['multisite'] ) ) {
	$subcommand = 'multisite-install';  // set command to create multisite 
}

$core_install = "wp --path=%s core %s --url=%s --title=%s --admin_user=%s --admin_password=%s --admin_email=%s";
WP_CLI::log( 'Installing WordPress...' );
WP_CLI::launch( \WP_CLI\Utils\esc_cmd( $core_install, $site_path, $subcommand, 'http://' . $args[0], $args[0], $admin_user, $admin_pass, $admin_email ) );
.....
...

I found no param to mentioned subdomain multisite and no way to add --skip-email param in current command.
