Upgrade ZK and configure autopurge

Nodepool now requires a newer version of ZK, so upgrade to 3.7, the
current stable version.

Also, configure the auto purge cleanup interval (6 hours) -- this will
instruct ZK to remove unused data snapshots every 6 hours in order to
avoid filling the disk.

Both of these changes have already been applied in production as
an emergency fix.
