Mohammed Naser 44608e16e7 wait-for-pods: Wait for all pods to become Ready
This refactors the code inside helm-template which waits for all
pods to become Ready to move inside it's own seperate role instead
which can be used for other tasks.

# NOTE(mnaser): When a StatefulSet is deployed, it creates the pods one
# by one, which means the `kubectl wait` can race if it
# is ran before the other pods are created. We instead
# check for all the StatefulSets here manually instead
# and then use the second check below to do a "confirmation"
