* Parameterize artifact configuration
**What**
- Add parameterization of artifact store configuration
**Why**
Enables configuration of artifact repo secrets or omitting for use with IAM credentials
* Add workflow CRD definition to argo chart
**Why**
The workflow CRD must exist in order for argo to function
* artifactRepository values follow tree structure
* Deploy CRD as a pre-install hook
**What**
Using `lachlanevenson/k8s-kubectl`, which appears to be the most popular, off the shelf container with `kubectl` applied, run a job to apply the `workflow` crd.
**Why**
CRD is not, and cannot, be parameterized with release and so attempting to deploy as a regular template causes failures when installing subsequent releases.
