Document how to create CR manually

[mmartin24]

We should document somewhere (to be discussed) how to recover Epinio app to be visible by CLI again if deleted.

Example:

cat <<EOF | kubectl apply -f -
apiVersion: application.epinio.io/v1
kind: App
metadata:
  annotations:
    epinio.io/created-by: admin
  name: jenkins-epinio
  namespace: workspace
spec:
  chartname: standard
  imageurl: jenkins/jenkins
  origin:
    container: jenkins/jenkins
  routes:
  - jenkins-epinio.192.168.16.3.omg.howdoi.website
EOF

Alternative: (edited. added post-initial description)

• Deploy a similar temporary app. Get app resources yaml from temporary and adapt that for the original one.

 k get apps.application.epinio.io jenkins-epinio -n workspace -o yaml > /tmp/sample.yaml

Modify & apply it

k apply -f /tmp/sample.yaml         

• Delete temporary app

epinio app delete temporary-app

App should re-appear

The intended recovery requires saving the custom resources before.
If they are not saved ...
