Commit Message

[IMPROVED] Implicit RePublish based on SubjectTransform (#7515)

If the stream configuration contains stream subject `a.>`, subject
transform `a.>` to `b.>` and republish `>` to `>`, this currently errors
containing a cycle. However, the intention behind this is that the
transformed `b.>` subject is RePublished. This PR now allows this, but
only if this link is preserved. Specifically only allowing if the stream
has a single subject and the transform maps only that subject. This is a
non-breaking change since this used to be an error before, and mostly
allows to not need to repeat the transformed subject of `b.>` two more
times in the source/destination of the RePublish.

Put simply, the `RePublish` of `>` to `>` gets transformed to a source
of `b.>` and destination of `b.>` given the prerequisites.
