> 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.
