Limit compared resources when no --selector option is used

[mjfernandezd]

While applying a template in a project with tailor we missed to add the --selector option resulting in the purge of all the resources in that project that were not in the template file.

Can this be limited in some way to avoid repeating the same issue in the future?

I deeply regret not making the default such that deletion of resources is prevented. It should have been like that. I think it makes sense to create a v2 (it would be a breaking change) of Tailor which requires --allow-deletion before it deletes resources.

For now, please make sure to review the displayed drift before you apply (e.g. stepping through each drifted resource). Also, I recommend to put a selector into a Tailorfile in the folder from which you are executing Tailor so that you cannot forget the flag.
