need use relaystate to resolve csrf when integrate saml2

[javasingle]

Some documents suggest using relaystate to pass csrftoken to solve CSRF attacks. Some documents suggest using relaystate as the callback address of successful login. When I use spring loyalty, I didn't find the processing of relaystate。

Spring Security's SAML 2.0 support does not yet verify the RelayState parameter in a SAML 2.0 authentication response. To achieve this, we need #9185.
