On Flexpool miners, workers and Etherscan dashboards, min, max and last
computations where based on multiple small time intervals instead of the big
time interval. Removing "group by" solved the computations.

Procedure to migrate:
Stop telegraf container:
```
docker-compose -f docker-compose.yml stop telegraf
```
Rename all measurements:
```
docker exec -it influxdb influx -unsafeSsl -ssl -database '$INFLUXDB_DB'
select * into flexpool_miner_balance from flexpool_balance group by *;
drop measurement flexpool_balance;
select * into flexpool_miner_stats from flexpool_stats group by *;
drop measurement flexpool_stats;
select * into flexpool_miner_workers from flexpool_workers group by *;
drop measurement flexpool_workers;
select * into flexpool_miner_paid from flexpool_paid group by *;
drop measurement flexpool_paid;
select * into flexpool_miner_daily_revenue_estimation from flexpool_daily_revenue_estimation group by *;
drop measurement flexpool_daily_revenue_estimation;
select * into flexpool_miner_payments from flexpool_payments group by *;
drop measurement flexpool_payments;
```
Update telegraf configuration.

On Flexpool dashboards, some values were printed in black. They were hard to
read on a dark theme. Revert back to default "green" value for improved
visibility on light and dark themes.
