When a Service Broker is called, meshcloud provides some meta data in the "context" item that you can query in your broker, such as "customer_id" or "project_id".
It would be good to have the tags from the meshCustomer and meshProject as well.
In addition, it would also be good to get the tenant IDs of the connected cloud projects as well. At the moment you'll only get this in the "BIND" operation, as it can be tenant-aware. I would like to have this tenant-awareness feature also for the PROVISION action.
