The official node_exporter reports node_time_seconds as a gauge, but
prometheus-node-exporter-lua reports it as a counter. To be consistent
with the official implementation, and because "gauge" is more correct
than "counter" for this metric (system time can decrease, but the
Prometheus documentation states, "A counter is a cumulative metric that
represents a single monotonically increasing counter whose value can
only increase or be reset to zero on restart."), change the type for
node_time_seconds to "gauge".

This exporter exposes information of the connected stations acquired
from hostapd. These contain additional information compared to the
existing station exporter, however they require a full build of hostapd
/ wpad.

To return the number of connected clients.
At present this can be partially inferred by using a count() over one of
the existing metrics, however this doesn't handle the case when there
are no connected clients. When that happens, the count() will return no
data instead of 0.

These output a count of the number of packets transmitted/received, so
should be tracked as a counter. As it stands, promtool is warning that
these shouldn't be named ending _total if they're a gauge.

If the /proc/sys/net/netfilter/nc_conntrack_* files are not present,
this exporter was outputting a blank value, which is invalid. These
files will not be present when using an image that doesn't include the
iptables and firewall packages (eg a minimal access-point type image).
This updates the collector to only output the metrics if the
corresponding /proc files are present.

Some releases may have non letters in it's name currently resulting in
an empty ("") output which is then discarded, resulting in *missing*
labels in the metric.
Now it uses `.-` to catch as little as possible, but anything.

prometheus-node-exporter-lua: bmx6/7 netjson format
adds labels called source and target to links instead of only the target
previously called "id".
Retrieving all *links* from prometheus now makes it easier to create
a valid netjson(.org) graph.
It's not feasible to use *instance* as *source* as for instance likely
the name is used for dns, instead of the ID. Using the *name* instead of
*id* for netjson linking results in a bad graph when two devices have
the same (default) hostname.

As prometheus-node-exporter-lua is a reimplementation of node_exporter,
I'm using "collector" instead of "scraper" and renaming some collectors
put each collector in a separate file
report collector success/failure and duration per scrape
(follow https://github.com/prometheus/node_exporter/pull/516)
allow to filter collectors using "collect[]" params
(see https://github.com/prometheus/node_exporter#filtering-enabled-collectors)
