Fix: Influxdb

STATE:
The influxdb database was configured to limit the number of value per
tag (Default: 100_000)

{"error":"partial write: max-values-per-tag limit exceeded
(100000/100000): measurement=\"speedtest\" tag=\"result_id\"
value=\"d35f2ff7-313c-4bff-941e-3b9c08484ae5\" dropped=1"}

FIX:
- Add a default influxdb configuration file
- Replace the configuration "max-values-per-tags" (ref:
  https://stackoverflow.com/questions/43770354/max-values-per-tag-limit-exceeded-influxdb)
