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.
