Remove LazyCsrfTokenRepository

[jzheaux]

As LazyCsrfTokenRepository is deprecated, it can now be removed.

Note that a number of components use setAttribute(HttpServletResponse.class.getName(), response) to store the response for later use by LazyCsrfTokenRepository. This ticket should also remove those references.

in place of LazyCsrfTokenRepository you can use CookieCsrfTokenRepository, itprovides a more secure and efficient way to manage CSRF tokens in Spring Security.
