Provide a docker image on dockerhub

[raweber42]

Is your feature request related to a problem? Please describe.
For using the Docker Image, it would be way easier to be able to just pull the image from dockerhub (or any alternative).

Describe the solution you'd like
A Docker Image is automatically created (maybe through GitHub Actions?) and pushed to a openly available registry. The Documentation is adjusted accordingly.

Describe alternatives you've considered
Let all users build the Docker images themselves.

Additional context
Especially useful for a kubernetes setup!

@guggero do you think this feature is what faraday needs at this time? I don't mind picking this up

[guggero]

Sure, that would be useful. Should be pretty straightforward, just need to copy and adjust https://github.com/lightninglabs/loop/blob/master/.github/workflows/docker.yml

[NonsoAmadi10]

awesome! I will be picking this up. Thanks! One small question:

Is the docker hub lightninglabs/faraday? @guggero

[guggero]

Is the docker hub lightninglabs/faraday?

Yes. I mean it doesn't exist yet (the first push will create it), but that's the repo name we'd want to use.
And it will only work after we've added the required credentials as GitHub repository secrets, which the repo admin will have to do.
