    Description

      After an ensemble-add, the zookeeper.url in the FUSE_HOME/instances/instance.properties does not get updated for a child container.

      Actual:

      item.1.opts = -server......... -Dzookeeper.url=\"172.17.80.22:2181\" ......

      Expected:

      item.1.opts = -server......... -Dzookeeper.url=\"
   172.17.80.22:2182,172.17.80.11:2182,172.17.80.8:2182\" ......

      The issue surfaced when a customer deleted the FUSE_HOME/instances/childcontainer/data/ directory. Upon restart, there were ConnectionExceptions (below) because the /data/../zookeeper.config file (having the updated zookeeper.url) was gone, and it seems that the old outdated one from instance.properties/zookeeper.url was being used instead.
