Dockerize Rover

[carlocorradini]

Trying fixing #719

Initial work attempting to dockerize Rover in the manner of Apollo Router.

Missing:

• rover-fed2 image. Tried without success. Need help!
• Fix CircleCI config.yml file.
• GitHub Packages serup for Rover under ghcr.io/apollographql/rover

Having a dockerized Rover image can be super useful in multiple situations: CI, CD, simple tasks, ...

Hey @carlocorradini - appreciate the work on this. At this time, we won't be publishing official Docker images for Rover as there isn't a great one size fits all approach, especially since rover supergraph compose cannot run on musl images due to its dependency on deno. You're likely better off extending your own applications image to download and install Rover - we try hard to make sure Rover has minimal requirements as far as other system tools go, and if you need rover supergraph compose, you'll need to do so on an amd64 image.
