Is your feature request related to a problem? Please describe.
I host arcane for my docker container management, and I would like to extend my arcane "cluster" via the use of the edge agents they provide. By default these edge agents connect via gRPC, however, netbird reverse proxy doesnt support, seemingly due to the lack of h2c support.

To note, arcane does provide a websocket fallback, however this can induce a lot of interruptions and is not ideal.

Describe the solution you'd like
Add an "h2c" option to the protocol options when adding a reverse proxy service target.

Describe alternatives you've considered
Falling back to the websocket option however as mentioned this is not ideal, plus if I want to deploy any other gRPC apps in the future, I will hit this same roadblock. The primary alternative ofc, is to use an external traefik instance (which i did previously), however this does not provide a nice web GUI, nor does it nicely integrate with netbird directly. Also, see the issue I raised here showing that external traefik support currently doesnt work. https://github.com/issues/created?issue=netbirdio%7Cnetbird%7C5830

I Thinking is really needed an a lot of the services I use require GRPC would be great if h2c support was enabled
