Feature request: support InfluxDB importer

[ligurio]

InfluxDB is a popular time series DB that often used as a datasource for Grafana for storing performance results.
I propose to implement InfluxDB importer for Otava in the same way as it was done for PostgreSQL ¹.
InfluxDB supports two query languages: InfluxQL ² and native SQL.

There are InfluDB clients for Python, however, Python libraries are different for different InfluxDB versions: v1³, v2 ⁴, v3 ⁵.

This would be a nice addition! Good news is that all Python clients have compatible licenses - MIT and Apache2.
