Description

Once we have reports from production users that the Curator zk plumbing introduced in AURORA-1468 is working well, the -zk_use_curator flag should be deprecated and then the flag and commons code killed. If the vetting happens before the next release (0.14.0), we can dispense with a deprecation cycle.
