e2e: retry kubectl commands in case deploying Vault fails

Browse Source 
Sometimes it happens that the deployment of Hashicorp Vault fails.
Deployment is one of the 1st steps that are done when starting the e2e
suite, and the Kubernetes cluster may still be a little overloaded while
it is settling down. It should be possible to retry and succeed after a
while.

Fixes: #2288
