InfluxDB 2.0: There is now way how to get version of InfluxDB from API [area/api]

[bednar]

The InfluxDB 1.7.x has defined /ping endpoint with X-Influxdb-Version header but in the API 2.0 there is no such thing.

The /health endpoint will be useful for that.

InfluxDB 1.8 "/health" endpoint already returns version:

{
"checks": [],
"message": "ready for queries and writes",
"name": "influxdb",
"status": "pass",
"version": "1.8.0"
}

Whereas the InfluxDB2.0 now returns

{
"name": "influxdb",
"message": "ready for queries and writes",
"status": "pass",
"checks": []
}

Adding a version string to 2.0 will fix this issue.
