RFE: updateDomain tool could inform if changes in configuration were made or not

[rssh22]

It could be very interesting to know if updateDomain makes real changes in the domain configuration or if the proposed model is the same than was previously configured.

For example, this information would allow admin users to know if the domain configuration was modified previously. It would also give a better integration with Ansible: check for possible changes before apply them.

There is the alternative of comparing previous domain model and post update domain model with the compare model tool, but it would be a lot more expensive in time for the user.

@rssh22 For your use case, is this an online or offline update? How do you get the "post update domain model" with which to compare? Why wouldn't you just keep your domain model under source control and add any changes directly to the domain model prior to running update? If there are no changes in source control, there is no need to update the domain, right?
