Migrate install Tekton release CD service to workspaces

[afrittoli]

Changes

Install Tekton release relies on the cluster PipelineResource
to target deployments of resources.

Migrate that to workspaces: a secret stored in the cluster bound
through a workspace is used to target the deployment.

Secrets have been preprovisioned on the cluster, their name is
tektoncd-, their type is kubeconfig.

See #887 for more details.

The change is implemented so that the template interface does not
change and thus all existing cronjobs are still valid as well as
the deployment script.

Fixes: #887

Added bonus, grep for PipelineResource on the plumbing repo yields no resources now!

@afrittoli Hey, look, a bug in plumbing-image-build - see https://dashboard.dogfooding.tekton.dev/#/namespaces/tekton-ci/taskruns/plumbing-image-build-l4dnb-images-build-00001-nt58r?step=build-and-push&view=details

It's trying to build the koparse image, but fails, because of this:

env:
  - name: FQ_DOCKER_FILE
    value: $(workspaces.source.path)/tekton/images/koparse/koparse/test_release.yaml

So it's trying to use tekton/images/koparse/koparse as the context and fails. Lemme see if I can fix.
