The non-superuser needs to have REPLICATION privileges atleast. A new function "subscription_cmd" has been added to allow running subscription related commands on datanodes. This function implicitly upgrades to the bootstrapped superuser and then performs subscription creation/alteration/deletion commands. It only accepts subscriptions related commands and errors out otherwise.
