Support for git@github in dependencies for schema generation

[haavardeide]

If a dependency is referenced with git@github release location instead of a relative reference ../versions, then schema generation will fail.

Solution: ensure that schema generation will work with both relative and github release:

  dependencies:
    - name: versions
      template-url: "[email protected]:oslokommune/golden-path-boilerplate//boilerplate/terraform/versions?ref=versions-v3.0.6"

  dependencies:
    - name: versions
      template-url: "../versions"

Schema generation should never make a main command to fail.

This could be decoupled from the CLI by hosting the schemas over HTTP.

Når man kjører ok pkg install så kræsjer den fordi den ikke støtter remote reference (kun lokal path)

Vurder å bruk https://github.com/hashicorp/go-getter for å støtte både mappe og git URI. Men vurder størrelsen på denne avhengigheten før vi drar den inn, dvs hvor mye større ok blir.
