Franz Pletz d432f9857e Use uint64 in the ZFS collector (#714)
ZFS metrics can also be unsigned 64-bit integers that won't fit in
int64 and causes the whole collector to fail.

Matthias Rampke e1f129c729 Use int64 throughout the ZFS collector.
This avoids issues with integer overflows on 32-bit architectures. The
Prometheus data format is float64, so regardless of the architecture we
should handle large numbers.

Fixes #629.

Tobias Schmidt 922e74d58f Remove unnecessarily named return variables
Named return variables should only be used to describe the returned type
further, e.g. `err error` doesn't add any new information and is just
stutter.

Joe Handzik e213ccbc57 ZFS Collector: Refactor to use maps/slices and fewer globals
Removed all global types that were unnecessary, and refactored to use constructor-created values and inline values instead of globals.

Christian Schwarz 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.
