Updates the upgrade configuration for the data source connections. This supports both upgrade and patch operations. Upgrade can be used to set the connector to the specified version whereas patch can be used to update a connector within the same version. Connectors within a connection would be upgraded or patched in a rolling manner. Specific operation status for a connection can be fetched using GET data-source-connection. If the connection is removed from the config after the upgrade or patch is issued internally by the system, the connection's operation status would not be updated for success or failure. Note that this is a config and action would be taken asynchronously at a later point in time, accordingly. Fields suffixed with UpgradePackageUrl must be used to upgrade connectors and those suffixed with PatchPackageUrl must be used to patch connectors.
