JSON "clients" inconsistebcy: "total" less than "wifi"

[RalfJung]

We occasionally see nodes with data like this in the hopglass JSON file:

        "clients": {
          "total": 1,
          "wifi": 2,
          "wifi24": 2,
          "wifi5": 0
        },

This is clearly nonsensical. A possible reason for this is that hopglass gathers these numbers through separate queries at different times. In an attempt to do better merging of these queries, it could use max(wifi, total) as the count actually printed into the JSON.

I believe this inconsistent data is given by respondd even in a single query.

"total clients" querries the current (batman) claimtable.
"wifi-clients" querries the wifi driver.
if batman and wifidriver have different gate times or different "keep alive/ttl-values": that's what gluon is reporting.
