ephemerals on ZK failure
What is the expected behaviour of ephemerals on disconnects?

Suppose a client creates an ephemeral and then, some time later, we have a
network failure, or ZK shuts down/crashes.

During this downtime, the client JVM is still up and running. What happens
when the ZK connection is re-established, does the ephemeral
get automatically recreated or does the client have to make an explicit call
to recreate it?
