Make Wekans MongoDB use a statefulset
Make Wekans MongoDB use a statefulset so it does not try to start a new pod before stopping the old one, as seen when updating Wekan on a live cluster:
root@oas:~# kubectl get pod -A | grep mongo
stackspin-apps wekan-mongodb-674ff9477c-9rd7x 1/1 Running 0 50d
stackspin-apps wekan-mongodb-64c95667cc-vdk5q 0/1 CrashLoopBackOff 211 17h
root@oas:~# kubectl logs -n stackspin-apps wekan-mongodb-64c95667cc-vdk5q
