First of all, apologies for re-opening this thread.

I think if the user is using providers screen to delete a repository, 
the intention is to completely get rid of it, otherwise they would've 
deleted the repository using a changeset. Also, if we don't provide a 
way to exterminate a given repo, the task of doing that can get very 
tedious, given sufficient number of environments that the repository was 
promoted to.

With this in mind:
   1. If the user attempts to delete a repo (from providers screen) and 
the repo was not previously promoted, allow the deletion to occur. (This 
is also today's behavior.)

   2. If the user attempts to delete a repo (from providers screen) and 
the repo was previously promoted.
     a. Show a confirmation dialog, warning the user that the repository 
will be deleted from all environments
     b. Delete repository from all environments if the user chooses to 
proceed.
