must set query-log-enabled = true when want to log slow query only.

Bug report

Influxdb version = 1.3.5

I must set 'query-log-enabled = true' when I want to log slow query.

when I configure the influxdb.conf below:
influxdb.conf
[data]
...
query-log-enabled = false

[coordinator]
query-timeout = "60s"
log-queries-after = "10ms"

The result is that influxdb didn't ouput log about any query.
Then I set query-log-enabled = true, I can see all query log including 'slow query log'.
I think it is not reasonable. May be have any better workaround to log slow query only?

Start by reproducing the supplied influxdb.conf settings, especially data.query-log-enabled and coordinator.log-queries-after. Trace how these options affect query logging and verify that the desired result is slow-query logs without logging every query.
