feat(jans-auth-server): add ability to propagate session from authz challenge script to grant object

Motivation: support 11600

Sample script

scriptLogger.trace("Authentication successful");
        context.getExecutionContext().setUser(user); // <- IMPORTANT : without user set, user relation will not be associated with token
        scriptLogger.trace("User {} is authenticated successfully.", username);

        // 4. referencing ROPC custom param script, need to enable authorizationChallengeShouldGenerateSession
        scriptLogger.trace("Creating Authentication session...");

        SessionIdService sessionIdService = CdiUtil.bean(SessionIdService.class);
        Identity identityService = CdiUtil.bean(Identity.class);

        Map<String, String> sessionStore = new HashMap<String, String>();
        sessionStore.put("login_id_token",login_id_token);
        sessionStore.put("login_access_token",login_access_token);
        sessionStore.put("transaction_status","PENDING");
        SessionId sessionId = sessionIdService.generateAuthenticatedSessionId(context.getHttpRequest(), user.getDn(), sessionStore);

        context.getExecutionContext().setSessionId(sessionId);
        // sessionIdService.updateSessionId(sessionId);
        // identityService.setSessionId(sessionId);
        scriptLogger.trace("Created Authentication session successfully");

It should be references in authorization grant object.
String sessionDn = authorizationGrant.getSessionDn();
