title: How to access destination service which is behind RabbitMQ using S4 Cloud SDK Connectivity
body: <p>We are using S4SDK to access destination service. it needs to work in multi-tenancy env. Normally if the app is a frontend app, the request context is triggered by user request. Accessing destination service with multi-tenancy is doable with approuter and XUAA. 
  In our case, our application is behind RabbitMQ which is not trigger by a user request (e.g. REST API call). Currently we are using the class com.sap.cloud.sdk.cloudplatform.connectivity.DestinationAccessor from cloud SDK. we can retrieve a tenant id out of message (RabbitMQ/AMQP). The issue is that we cannot find a way to inject the tenant id or clone a JWT token into DestinationAccessor from S4SDK. We look for a way/guidance of how to achieve that. We expect this exchange/clone token is provided by the SDK.</p>
