InfluxDB2 custom component for ESPHome

Changes from Jepsson/esphome-influxdb:

Changed to InfluxDB2 API
Made usable as external component
Remove "device" as it can be replaced by a tag
Made tags by sensor usable
Added option to switch to https
field_key can be set manually

Update notes for ESPHome 2024.06

With ESPHome 2024.06 the http component was rewritten. Therefore this component had to be updated. In regards to this component the user has to do nothing. However, as the http component is utilized the corresponding configuration variables for ESP8266 have to be set, see: HTTP Request.

This means setting

http_request:
  verify_ssl: false

for ESP8266.

ESPHome older than 2024.06

For ESPHome older than 2024.06 include the code as
