58f50b31f2 Multiply port data XMIT/RCV metrics by 4 (#579) 
According to Mellanox, it is standard practice that the port_xmit_data and port_rcv_data
files are split into 4 lanes. To get the actual transmit and receive values for each
port, the metric needs to be multiplied by 4.

bb9d4ade0b uname_linux: Build for 32bit MIPS too 
Since Go 1.8 32bit MIPS Big/Little Endian are supported assuming the
target runs Linux and the kernel either emulates an FPU or can access
the CPU one.

This allows the node_collector to build for mips and mipsle opening up
the possibility of running it on things like home routers
(DD-|Open|ASUS-)Wrt firmware usually has the necessary bits in place.

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.
