spk reconcile should use fab add --type helm

[evanlouie]

Describe the bug: spk reconcile should specify --type helm when doing
fab add when adding the helm chart component to a ring.

See:

• https://github.com/CatalystCode/spk/blob/master/src/commands/hld/reconcile.ts#L366
• https://github.com/CatalystCode/spk/blob/master/src/commands/hld/reconcile.ts#L368

To Reproduce: run spk reconcile on a bedrock project with at least one
service with a valid IHelmConfig. Note the created component for the helm chart
is of type component. Causing fab install to fail.

• mkdir app hld
• cd app
• spk project init
• spk service create my-service -n traefik -b master -p traefik -g https://github.com/containous/traefik-helm-chart.git
• cd ..
• cd hld
• spk hld init
• cd ..
• spk hld reconcile my-app-component hld app
• cat hld/my-app-component/my-service/master
  • will yield:

    name: master
    type: component
    subcomponents:
    - name: chart
      type: component # should be of 'helm' instead of 'component'
      source: https://github.com/containous/traefik-helm-chart.git
      method: git
      path: traefik
      branch: master
    - name: static
      type: static
      method: local
      path: ./static
    

• subcomponent chart should be of type: helm not type: component

Expected behavior: spk reconcile works properly and the underlying
fab install calls install the components correctly.
