We previously did not identify the correct BSS from the output of
`hostapd_cli -i <phy> status`, because when asked for a vif it will
always respond with information relevant to the whole phy.
The per vif settings will use an iterator and we now try to detect
the correct BSS from that output.

There was a corner case, when a vif had no stations, that
evaluate_metrics for a station that was nil and had no collected metrics
would have been called.
Comment the code, to make it easier to understand and follow, and

Normalizes metrics according to the Prometheus upstream metric
guidelines available at https://prometheus.io/docs/practices/naming/.
Drops the `hostapd_station_wpa` metric, because it is misleading, as it
is not a differentiator between WPA versions, like one could be led to
assume.
Exposes more flags in a more consistent manner. Their metric was
previously only exposed if the flag was present, but not if it wasn't.
The same applies issue was fixed with regards to vht caps.
After this commit the following breaking changes are in place:
- All flags have been moved below `hostapd_station_flags_$flagname`:
- `hostapd_station_ht` is now `hostapd_station_flag_ht`
- `hostapd_station_mfp` is now `hostapd_station_flag_mfp`
- `hostapd_station_vht` is now `hostapd_station_flag_vht`
- `hostapd_station_wmm` is now `hostapd_station_flag_wmm`
- New flags have been exposed:
- `hostapd_station_flag_he` for high-efficency connections
- `hostapd_station_flag_short_preamble` for short preamble connections
- `hostapd_station_flag_auth` for authentication state
- `hostapd_station_flag_assoc` for association state
- Some metrics have had their unit normalized to the SI base unit or
embedded into the metrics name:
- `hostapd_station_inactive_msec` is now
`hostapd_station_inactive_seconds`, the value is still float64 and
as such has enough precision anyway, but becomes easier to reason
about
- `hostapd_station_connected_time` has been renamed to
`hostapd_station_connected_seconds_total` so the unit, as well as
the nature of the counter is reflected
- `hostapd_station_signal` now includes its unit and is therefore
named `hostapd_station_signal_dbm`
- The packet counter metrics have been normalized to what the node
exporter uses, so it is more in line with the defaults in the
Prometheus ecosystem:
- `hostapd_station_rx_packets` is now
`hostapd_station_receive_packets_total`
- `hostapd_station_rx_bytes` is now
`hostapd_station_receive_bytes_total`
- `hostapd_station_tx_packets` is now
`hostapd_station_transmit_packets_total`
- `hostapd_station_tx_bytes` is now
`hostapd_station_transmit_bytes_total`

Correlating data is only possible when we have more metadata, this adds
a bunch of labels for each client, that will increase the depth of
dashboards yet to come.
In particular the changes in this commit are:
- renames the `ifname` label to `vif`
- adds `frequency`, `channel`, `bssid`, `ssid`, `encryption` and `mode`

There is already the hostapd_stations exporter, which uses
hostapd-utils (more precisely hostapd-cli) to get client statistics.
However, the ubus interface is permanently integrated under hostapd
in OpenWrt. So this exporter needs one dependency less.
For now it exports mainly the rrm statistics. Many people are
interested in what your device supports. The exporter provides
information about the radio-resource-managment extensions.

Extract data from configuration file /etc/config/dhcp and create labels
{name, ip, mac, dns} via uci. Those labels are useful in order to craft
complex prometheus queries as replacing the MAC address to a custom
name. E.g.: wifi_station_signal_dbm * on (mac) group_left(name)
uci_dhcp_host or on (mac) label_replace(wifi_station_signal_dbm, "name",
"$1", "mac", "(.+)")

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".

Drop the config knob 'listen_address' and introduce 'listen_interface'
and 'listen_ipv6' instead.
'listen_interface' takes an openwrt interface name ('loopback', 'lan',
'wan' etc, or "*" for all), from which the primary IP is used to listen
on. If 'listen_ipv6' is set to '1', the IPv6 adress will be used, IPv4
elsewise.
procd interface triggers are now combined with this, so if the listen
interface is not yet configured when the init script is executed, the
process start is defered, and the trigger takes care of that once
the interface is ready.

To return the number of connected clients.
At present this can be partially inferred by using a count() over one of

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.

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.
