modules/services/colima: init

[will-lol]

Description

Adds a colima service. This service will be useful to darwin users who would like to run containers on their computer. It is based on this PR in nix-darwin, but I determined it to be more practical to be in hm. This PR depends on my other PR that adds docker context support.

Colima also supports linux, but is far less commonly used. Still, I have built this hm module to support linux. I have tested it to the best of my abilities without access to a bare metal machine. If someone could give it a spin that would be amazing!

These changes will allow users of nix on darwin to:

• Enable container support in a few lines of configuration
• Easily have and switch between multiple docker hosts. This is particularly relevant as more options become available for containerisation on darwin (https://github.com/apple/containerization)

Now that my other PR is merged, this one is ready to be considered.
I still don't have access to a bare metal linux box to test this unfortunately! It would be amazing if someone could give this module a spin on linux.
