Operator fixes, Tekton guides

[akochnev]

This is a cumulative PR of the last few sets of changes, all rolled in one:

• A set of fixes for the end-to-end pipelines that get deployed with the project. These will need some more work to sync them up with the final state of the pipelines that are created in the labs, but these work.
• A set of updates to the OpenShift serverless operator to use the redhat operator (instead of community)
• A set of updates to the Jenkins operator which makes the jenkins pipelines build configs work out of the box
• The Tekton based set of guides (15 out of 16 labs) that implement the DevSecOps pipeline (the equivalent of the Jenkins pipeline from the 3.x workshop). The only one that is still missing is the STIG scan. The guides are still likely going to need some editing and work - this was mostly a first pass that makes things work, but I haven't taken a second pass to make verify things end-to-end.

One thing to note is that there is a timing issue with the OpenShift pipelines operator which makes the devsecops playbook fail the first time (as the operator takes a bit of time to provision the pipeline service account), which makes the playbook fail the first time. Running it a second time goes through.

I suggested a few mods in a PR to your branch https://github.com/akochnev/openshift-devsecops/pull/1: I've also built an image with your new guides in case you want to see the feel in the workshop-dashboard. Just set workshop_dashboard_image: quay.io/akrohg/devsecops-workshop-dashboard-tekton:latest in the workshop-spawner role's vars.

We'll need to add tkn to the workshop terminal as well - I'll create a separate issue and tackle that in the meantime

@andykrohg - good stuff. I accepted your PR in my branch, so this PR has the cumulative changes.

One small fixup for CRW/Keycloak deployment objects which I'll commit after. Otherwise, LGTM!
