fix(git): allow specifying git refs for sources

This allows, e.g., pointing at a particular Gerrit Patch Set using
natural configuration, e.g.:

    ---
    schema: armada/Chart/v1
    metadata:
      schema: metadata/Document/v1
      name: ceph-config
    data:
      chart_name: ceph-config
      release: ceph-config
      namespace: ucp
      timeout: 3600
      install:
        no_hooks: true
      upgrade:
        no_hooks: true
      values: {}
      source:
        type: git
        location: https://github.com/openstack/openstack-helm
        subpath: ceph
        reference: refs/changes/54/457754/73
      dependencies: []
