8c23f5ff54 ZFS Collector: Convert dashes to underscores for metrics
This fixes #442, and prevents other ZFS metrics from slipping through in the future.

Removed all global types that were unnecessary, and refactored to use constructor-created values and inline values instead of globals.

f29f3873ea Add a collector for ZFS, currently focussed on ARC stats.
It is tested on FreeBSD 10.2-RELEASE and Linux (ZFS on Linux 0.6.5.4).

On FreeBSD, Solaris, etc. ZFS metrics are exposed through sysctls.
ZFS on Linux exposes the same metrics through procfs `/proc/spl/...`.

In addition to sysctl metrics, 'computed metrics' are exposed by
the collector, which are based on several sysctl values.
There is some conditional logic involved in computing these metrics
which cannot be easily mapped to PromQL.

Not all 92 ARC sysctls are exposed right now but this can be changed
with one additional LOC each.
