Shalin Shekhar Mangar 5670d612e3 SOLR-11990: When a Collection CREATE command fails because of a policy rule violation, the collection metadata remains in ZooKeeper, even though no replicas are added, so the user has to manually delete the zombie collection.
This is due to a change in behavior made in this issue where collection metadata creation was moved before attempting to use policy to place replicas. This change reverts the behavior by explicitly deleting the metadata when an AssignmentException occurs. Since the policy depends on collection metadata such as WITH_COLLECTION and COLOCATED_WITH properties, moving metadata creation after policy use would have resulted in passing these properties through the entire call stack quite invasively. Therefore the current approach is adopted.
