[pve-devel] [PATCH manager] status: influxdb: always quote tags

[Dominik Csapak]

Since tags are mostly free-form, a single tag with a numeric value will
get sent to influxdb as a number by default. Change that to always quote
the tags as a string, like we do for the 'name' field. (InfluxDB can
only have one type per field, so either a string or a number type).

This won't fix influxdb databases after there are already numeric values
in there, but I guess most tags won't be purely numeric, so this won't
be an issue for most users, and fixes the reverse case where purely
numeric tags won't show up in influxdb.
