Idea:

• extract all values in 1 go, instead of many connections with http/zbx protocol options and prometheus format for HTTP endpoint, JSON for ZBX protocol

Why:
1. Instead of making a lot of small connections, take all the default data which can be extracted with 1 request
2. Interoperability, instead of running some Prometheus exporter and Zabbix for different things, Agent can replace exporter, and be used in a mixed environments (some environments execute 17 monitoring tools with custom build unified web frontend, which uses API to manage all this systems).
