prometheus-node-exporter-lua: Add wifi_station_count

Browse Source 
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.
