Description

~~SOLR-7245~~ added a retryOnConnLoss parameter to ZkController.ensureReplicaInLeaderInitiatedRecovery so that indexing threads do not hang during a partition on ZK operations. However, some of those changes were unintentionally reverted by ~~SOLR-7336~~ in 5.2.

I found this while running Jepsen tests on 5.2.1 where a hung update managed to put a leader into a 'down' state (I'm still investigating and will open a separate issue about this problem).
