Support receiving data from the Zabbix connector with API `/zabbixconnector/api/v1/history`
Labels:
- The metric name is added to the `__name__` label.
- Host name to `host` label.
- Visible name to `hostname` label.
The returned response complies with the requirements of the Zabbix
See the following doc for connector [protocol](https://www.zabbix.com/documentation/current/en/manual/config/export/streaming).
