Support to update secrets multiple times

[csakshaug]

It could be nice to have possible not only create secrets the first time you run ofc-bootstrap, but it could also be helpful to update all the secrets at once if need or make it easier for testing/developing

Expected Behaviour

Instead of running multiple kubectl create commands we collect all of the secrets in own yaml file that we apply with kubectl apply -f secrets.yaml

Current Behaviour

Today you have to edit or create a yaml file manually for every secret.

Possible Solution

Added a flag that gives that behaviour
