Support Elytron specific callbacks with JASPIC ServerAuthenticationModules

JASPIC already supports the use of a CallbackHandler for communication between the ServerAuthenticationModule and the container the first stage of implementation is to support the callbacks mandated by the spec - this task is to follow up and add support for Elytron specific callbacks.

The reason to split this out is we may still want to handle our core lifecycle related callbacks so of the remaining callbacks we will need to decide which ones we want to support.
