Provide extendend SAML logging (like SAMLDefaultLogger)

Expected Behavior

We would like to have the possibility to easily log SAML responses as with the (previous) SAMLLogger-API.

Current Behavior

We did not find a "standard" way of logging details of the SAML response.

Context

We are currently migrating from Spring Security SAML Extension to the new Spring Security Service Provider library. We have used a SAMLDefaultLogger bean to have an extensive logging of the SAML response (e.g. in the old SAMLAuthenticationProvider).
In the new library we did not find something like the old SAMLLogger-API and in the new OpenSamlAuthenticationProvider, the logger does only log pretty basic information.

Are you planning to port this feature or do you recommend overriding e.g. the AuthenticationProvider for adding more logging?
Thanks!
