Description

Currently the only way users can impersonate another user is by creating a NimbusClient explicitly by passing a doAsUser Param. We should allow a config value "doAsUser" to ensure users can submit this config as part of storm jar command. This will be useful for storm-rest/ui component which now has the ability to submit topology. Using this config value the ui server can submit a storm topology on behalf of another user and the topology will still execute as the submitter.
