NC pod gets killed too fast during installation

A fresh install of NC (see #1020 (closed)) lead to this:

This currently uses the default probes from the Nextcloud chart. We can either raise the issue upstream or override the probes in our helm chart. I'd love to trust upstream in this case, but maybe it's not the wise option

So my proposal would be to add this to our values (as we have it overwritten in stackspin/stackspin right now):

nextcloud:
  startupProbe:
    enabled: true
    failureThreshold: 60

changed milestone to %0.8.2

Can be done in conjunction with #965 (closed)
