Update hyper crate deps (major)

[tchapacan]

The tool is based an a rework of this crate => https://crates.io/crates/livebox/

I have modify this crate and embedded it in this codebase to be able to add more queries and retrieve more metrics for the exporter. It seems that it uses as dependency hyper:

Current version used as dep:

hyper = { version = "0.14.19", features = ["full"] }

Hyper is now https://crates.io/crates/hyper at version 1.2.0, and we need to keep it up to date. Unfortunately it comes with breaking change as the exported types have changed so client.rs need to be adapted now

prometheus_exporter_base should be updated as well, there is an ongoing PR which would help a lot MindFlavor/prometheus_exporter_base#32 awaiting to be merged (if it will be, or seek alternative solutions)
