Mark Miller updated SOLR-9834:
------------------------------
Description:
The results of this have annoyed me for some time. We should fail rather than
create the collection node and only ensure the rest of the path exists if the
collection node did not need to be created.
Currently, leader elections can trigger on delete and recreate a collection zk
node that was just removed. I think there was a bit of defense put in against
that, but I still see it and this is more thorough as well as a step towards
the ZK=Truth path.

> A variety of spots in the code can create a collection zk node after the
> collection has been removed.
