Difference from zookeeper_exporter?

[carlpett]

Hi! I wonder what the differences are between this exporter and zookeeper_exporter? They seem to use a similar method with sending mntr (although this one also sends ruok, which the other one does not). Unless there are major differences that warrant having two different implementations, perhaps they could be merged?

As I can see, this exporter allows to monitor multiple zk instances at once.
