Collect the InfiniBand port state, the physical state, and the maximum
signal transfer rate.

Parsing the sysfs files for InfiniBand was added to the procfs library
(see https://github.com/prometheus/procfs/pull/164).
Therefore use `InfiniBandClass` from the procfs library instead of
parsing sysfs itself.
If the port counter return `N/A (no PMA)` no metric will be returned
(instead of returning 0 for this metric.

* Improve stat linux metric names.
cpu is no longer used.
* node_cpu -> node_cpu_seconds_total for Linux
* Improve filesystem metric names with units
* Improve units and names of linux disk stats
Remove sector metrics, the bytes metrics cover those already.
* Infiniband counters should end in _total
* Improve timex metric names, convert to more normal units.

for what stabil means, looks like a moving average of some form.
* Update test fixture
* For meminfo metrics that had "kB" units, add _bytes

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.

Older versions of the OFED drivers contain 64-bit variants of the port counters and are located in a directory named 'counters_ext'. This patch includes these older metrics that have since been deprecated with OFED 4.0.

In case a metric file within the InfiniBand collector doesn't exist, skip the metric in order to allow collection of the remaining valid InfiniBand metrics.

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.
Add new metrics for the InfiniBand network protocol including the amount of packets sent and received, the number of times the link has been downed and how many times the link has recovered from an error state.
