Idea: make register url configurable about headscale

@sim-san sorry to hear that. Will close the issue now.

Hey @sim-san,

Sounds good to me. Although I reckon at some point you will need some kind of internal API provided by headscale.

@kradalby any thoughts on this?

A webui would be neat, however I think we would benefit from a bit of a refactoring before that work is started.

We currently have a CLI tool that talks directly to the database and sometimes communicates by having the serve mode watching database tables. What we probably should to, to make it easier to use the CLI tool on another computer, and to avoid update and state issues in the database because the CLI changed something the server has loaded.

Doing that work, which is making an API that the CLI uses, forcing us to implement an API for all of the CLI, we should have a suitable API for a webui.

I think that we should bite the learning curve and use protobuf and gRPC to design and generate the client/server code for the CLI, and then use something like https://github.com/grpc-ecosystem/grpc-gateway to make a JSON API out of it.

This way we should also be able to generate a lot of the code for a webui for interacting with the API.

This is quite an undertaking, and I was hoping to start playing around with it at some point.

Feedback on the approach is welcome.

Due to personal circumstances I will not be able to work on it in the future
