Disable Zookeeper Prometheus export
...
This does not work as this functionality is built out of the Debian
packages. Hopefully it will be enabled one day...

Unify and standardize inventory_hostname
...
This was causing some confusing conflicts, so create a new fact called
"this_node" which is inventory_hostname.split('.')[0], i.e. the short
name, and use that everywhere instead of an FQDN or true inventory
hostname.

Disable any systemd start rate limiting
...
Because Zookeeper is supremely stupid (see last commit) we want to
disable start limiting. It needs to keep trying forever until it starts.

The Zookeeper daemon does not appear to exit with any status other than
0, even after a fatal error. Work around this.

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.
