Summary:
In order to support this the stream inceptor transform nodes now is able to return a list of new meta enties, since these are new attributes we try to mimic what would have happened if they were generated on the client. This makes the rest of the logic downstream simpler
Introduced metadata register, same idea as on the clients.
The attributes available are a mixed bag, will work with blok server to imporove

Summary:
Added stream interecptor which gets a chance to augment the messages off the wire. Stream interceptor transformations are async and can fail due to network errors so added error state with a retry button. The retry button will just call the function again.
I am also handling errors better generally when this method fails unexpectedly, logging more clearly what went wrong and communicating it to the user
Did some refactoring of subtree update event to support this
