SEC-2504: CAS Clearpass extension

[spring-projects-issues]

Provide a way to easily retrieve the principal's password.via the Clearpass extension for CAS.

Once you have:

• Properly configured CAS server clearpass machinery
• Spring Security client side standard CAS with proxy tickets config
• A tiny bit of this ClearPass config (basically it's just a CasAuthenticationProvider bean replacement)
• ...then retrieving a password (after a successful CAS authentication of course) is just a matter of obtaining UserDetails instance from SecurityContext and calling UserDetails#getPassword.

We have already implemented this feature here: https://github.com/Unicon/cas-java-clients-addons/wiki/Spring-Security-CAS-ClearPass-Extension

I am hoping to be able to submit a pull request shortly.

CAS does not provide support for Jakarta APIs and thus the support is dropped in 6.0.x If this changes, then we will consider this issue if there is continued interest
