Description

It's currently impossible to create a CloudHttp2SolrClient with a custom ClusterStateProvider, e.g. a ZkClientClusterStateProvider with an existing ZkStateReader. This issue aims to address that somehow. CloudLegacySolrClient does have this ability!

It must be addressed (and used in ZkController) to prevent a possible performance regression here, which switched from a CloudLegacySolrClient to CloudHttp2SolrClient but without using the existing ZkStateReader and possibly a chroot bug .
