Ivan Kozlovic 9975a38c6e [FIXED] JetStream: stream sources issue in mixed mode clusters ...

The main issue was that in mixed-mode, the interest through gateway
may still be in optimistic mode, which when creating the source
consumer would start delivery before we had a chance to setup
the subscription to receive those messages.

The approach is to create the subscription prior to sending
the consumer create request. Also refactored a bit the code in
the hope to make the retries a bit more bullet proof.

We may also look at making sure that gateways are switched to
interest-mode when detecting a mixed-mode setup.

Also fixed a defect that could cause a source to be canceled
when updating a stream.
