Impact of the new feature
MSTransferor

Is your feature request related to a problem? Please describe.
MSTransferor can generate alerts for misconfigured workflows, which are delivered to our email inboxes. Here is one example [1].
We should be able to configure whether we want these alert/notifications to be created or not.

Describe the solution you'd like
In addition to checking with the Monitoring team who is supposed to be getting such alerts, we need to implement the following features:

• create a service configuration that can be used to enable/disable these notifications
• change services_config test environment to have it disabled by default
• change MSTransferor code to respect the relevant configuration

Describe alternatives you've considered
Keep dealing with these unwanted alerts.
