Implement InfluxDB preset

[orlangure]

A short guide on implementing a new preset:
https://github.com/orlangure/gnomock/blob/master/CONTRIBUTING.md#new-presets

MySQL preset for inspiration:
https://github.com/orlangure/gnomock/tree/master/preset/mysql

The objective is to implement a new Preset that spins up InfluxDB docker container, sets up its initial state (user provided data), waits for it to become ready and kills it in the end.

Please note that there are multiple steps required to create a new preset (see the guide above).
