feat(argo-workflows): added initial support for Argo workflows

[jakepage91]

I added support for Argo-workflows. I have tested it and it works.

It turns out the that deployment was of argo-workflows was not to be deployed in the argocd namespace, the docs recommends for it to be deployed in the argo namespace.

One thing that I noticed regarding the Entrypoint is the following peculiarity that some users might find confusing:

Note: The URL uses https and not http. Navigating to http will result in a server-side error.
Due to the self-signed certificate, you will receive a TLS error which you will need to manually approve.

It seems like your change removed a bunch of new lines at the end of untouched files.

I find it a little wired that argo recommends following namespaces:

• argo-cd -> argocd
• argo-workflows -> argo
• argo-events -> argo-events

@christophenne @kosmoz what would be your opinion in installion all argo packages into a argo-system namespace ?
