SEC-2503: CAS Clearpass extension

Misagh Moayyed (Migrated from SEC-2503) said:

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.
