Sort snowflake-ips stats by country count.

We currently don't sort the snowflake-ips metrics:

snowflake-ips CA=1,DE=1,AR=1,NL=1,FR=1,GB=2,US=4,CH=1

To facilitate eyeballing our metrics, this patch sorts snowflake-ips by value. If the value is identical, we sort by string, i.e.:

snowflake-ips US=4,GB=2,AR=1,CA=1,CH=1,DE=1,FR=1,NL=1

This patch fixes #40011 (closed)
