   We used to pass the workload to a K8s worker using command line args which 
is not a good practice.
   
   Through this PR, I am create a K8s Secret to pass in the task workload: 
https://kubernetes.io/docs/concepts/configuration/secret/. The secret will be 
containing the ExecuteTask workload
   json and it will be mounted into the worker pod at a fixed path. The pod 
reads the workload using` --json-path` instead of `--json-string`. Lifecycle of 
the secret is managed too, ie: the secret is deleted after the task completes 
or if pod creation fails.
   
   ### Sizing implications?
   
   Each Secret will be under 1 KB or less in size considering the standard 
fields it will have and the structure we form, making the overhead negligible 
even at high concurrency. 
   
   Since the scheduler now would require creating a K8s secret for the worker 
to mount it,  the helm chart pod-launcher RBAC role has been updated to grant 
the scheduler permission to create, get, and delete secrets, which doesn't seem 
too bad since scheduler is a trusted component and on top of that, already had 
the same verbs for "pod" role.
