Add auth. header to /os/v1/config requests

Add auth. header to /os/v1/config requests

Allows the API to identify devices requesting configuration and apply routing logic (e.g. switch from TCP to UDP OpenVPN configuration).

In the not-so-distant future we may chose to begin switching devices from the default TCP OpenVPN configuration, to stateless UDP config, to reduce load on the backend and increase reliability of the VPN (Cloudlink) connections. This change adds Authorization header to requests {{api}}/os/v1/config endpoint, with which the API can begin identifying devices and depending on device config vars/model returning the relevant OpenVPN (or other type of configuration).

@ab77 why not PR this directly into os-config? We don't maintain patches in meta-balena for sources we own.

I was under the impression we can not build os-config outside of Yocto to make it work with balenaOS cc @Page- @klutchell

Happy to make the change directly in the os-config via a PR, and personally, I don't particularly care which way this is done, as long as it ships reasonably soon so we can start identifying devices at the config stage @alexgg

Just for the record, this PR is likely to be more impactful than os-config/pull/75, since the later can't (yet) be built with Rust tooling in the Yocto framework and therefore can't make it into the runtime OS. cc @klutchell @alexgg

@alexgg this was discussed in a brainstorm and decided that merging this should be fine to get the ball rolling on device support and then the scarthgap work of @klutchell and @floion will include removing the patch with the updated os-config
