   This only addresses driver, what about executors if they have sidecar injected too? The executor must wait as well before sidecar container is ready and then make bootstrap calls to driver.
   
   I was getting connection refused excp because sidecar container was not ready and executor was trying to communicate. I resolved it by adding a sleep/wait time in entrypoint.sh for exec, but it would be neat to have a `spark.k8s` config which allows to set wait time.
