Can't modify 60s query timeout threshold not enough (bigquery)

Metabase throws “Query timed out” error for query that takes longer than 60 seconds in bigquery. Seems tied to https://github.com/metabase/metabase/issues/1749. The 60-second value is hardcoded in line 128 of /modules/drivers/bigquery/src/metabase/driver/bigquery.clj. Could this be modified to accept an environment variable for this value?

Metabase version 0.34.1

Hi @brendan
It seems like there might be 60 seconds timeout on BigQuery and Druid, when looking in the drivers. All other drivers doesn’t have timeouts (from a quick look), so it feels like a legacy thing.
https://github.com/metabase/metabase/blob/master/modules/drivers/bigquery/src/metabase/driver/bigquery.clj#L128
https://github.com/metabase/metabase/blob/master/modules/drivers/druid/src/metabase/driver/druid/query_processor.clj#L149
I’m not sure if I’m reading the code correctly, so I’ll try to ping @sbelak to see if it’s correct (and if I should open an issue on it).
