/**
* The security handler responsible for attaching the SecurityContext to the current {@link HttpServerExchange}.
*
* This handler is called early in the processing of the incoming request, subsequently supported authentication mechanisms will
* be added to the context, a decision will then be made if authentication is required or optional and the associated mechanisms
* will be called.
*
* In addition to the HTTPExchange authentication state can also be associated with the
* {@link io.undertow.server.protocol.http.HttpServerConnection} and with the {@link io.undertow.server.session.Session} however this is
* mechanism specific so it is down to the actual mechanisms to decide if there is state that can be re-used.
