Josh Cummings 3c46727be1 Transient Authentication Tokens
This commit introduces support for transient authentication tokens
which indicate to the filter chain, specifically the
HttpSessionSecurityContextRepository, whether or not the token ought
to be persisted across requests.

To leverage this, simply annotate any Authentication implementation
with @TransientAuthentication, extend from an Authentication that uses
this annotation, or annotate a custom annotation.

Implementations of SecurityContextRepository may choose to not persist
tokens that are marked with @TransientAuthentication in the same way
that HttpSessionSecurityContextRepository does.
