Zabbix template - plugin (#22)

* Initial upload

A yaml that can be imported to zabbix to add monitor data to it. See readme for full info

* each discovered item becomes a host

Made a change that will allow each node and each vm that is discovered to be registered as host, with it's own sub-items. this makes navigation a lot easier

* Added graphs and dashboards for all elements

* lowered delays to make template poll less
