* remove the need to have query feature support
Some InfluxDB servers don't have /query support feature but are still valid servers for storing data.
Usually those servers are proxies to others timeseries databases.
The change proposes to still validate the configuration but with less requirements on the server side.
* `.query` call is replaced by `.write_points`
* no more query call in the influxdb component. remove test
* reset mock after the setup and before the test
* remove unused import
* reset mock stats after component setup
