expose or not InfluxDB API

[cskiraly]

Apart from our own API, there is a question whether to expose the InfluxDB API.
There are clear advantages (e.g. using InfluxDB specific nodes) and disadvantages (e.g. exposing the implementation).

The proposal from @nopbyte was not to expose it by default, but leave it user configurable.

Yea I agree, atm it's configurable by adding an EXPOSE statement to the docker compose file.

OK, lets keep it like that till we figure our how to expose such config options towards a user.
