InfluxDB v2 support

[pavel-odintsov]

Hello!

Customer reported on Telegram that we do not support InfluxDB v2:

2023-09-18 21:31:59,815 [DEBUG] InfluxDB write operation failed for total_traffic
2023-09-18 21:31:59,816 [DEBUG] InfluxDB batch operation failed for networks_traffic with error
2023-09-18 21:31:59,817 [DEBUG] InfluxDB batch operation failed for hosts_traffic with error

Quote:

it works with tokens auth, but in the fastnetmon configuration i can provide only user/password auth

Some intermediate solution can be used: https://docs.influxdata.com/influxdb/v2/reference/api/influxdb-1x/#authenticate-with-a-username-and-password-scheme
