Add jute.maxbuffer to Zookeeper environment ops Adds this option based on the findings of https://github.com/python-zk/kazoo/issues/630, whereby restores of >1MB in size would fail. This is considered an unsafe option, but given our usecase no actual znode should ever exceed this limit; this is purely for the large transactions that come from a `pvc task restore` action to an empty Zookeeper instance.

# java.net.preferIPv4Stack=True
# Prefer IPv4 over IPV6 to avoid strange headaches in mixed environments.
# jute.maxbuffer=67108864
# Increase the maximum buffer size from 1048575 (1MB) to 67108864 (64MB); required to allow a single `create`
# transaction, in the /api/v1/restore specifically, of >1MB of data; 64MB seems a reasonable limit given my
# cluster is only ~5.2MB of raw JSON data and beyond 12x that seems like a cluster too large for PVC.
Tune Zookeeper memory usage Use Xms and Xmx=128M to reduce overall Zookeeper memory usage.

# Xms/Xmx=128M
# Reduce the Java memory size to minimize RAM consumption by Zookeeper.
