> When reestablishing Zookeeper session after expiration, Solr has to re-register all cores to Zookeeper (join leader election...).
> Currently, code is bloated and iterates over all cores instances just to get the name and metadata (CoreDescriptor).
> Proposal is to remove the core supplier and just call {{CoreContainer.getCoreDescriptors()}} for such iterations. Iteration will be slightly more efficient.
