I think key value pairs are too generic and can get very confusing to make sense of. I dont think we'll be adding too many such options to the submission context, so I'd prefer an API to make it explicit and less confusing to use.

> The RM and NM do not read a job's configuration. Clients / AMs should however be able to configure certain parameters for the RM/NM on a per app basis - like the Log Retention policy, token cancellation.
