cmd, metrics: add support for influxdb-v2 (cherry-picking from italoacasas' changes), leave existing support for v1 to maintain backwards-compatibility. (#23194)

This PR adds flag to enable InfluxDB v2 (--metrics.influxdbv2), flags for v2-specific features (--metrics.influxdb.token, --metrics.influxdb.bucket), also carries over addition of support for specifying organization (--metrics.influxdb.organization), but still retains backwards compatibility with InfluxDB v1.
