Solution for mass-assigning deploy keys
From customer: Our situation is that we have projects divided into multiple repositories (because they are kindof modularized), and adding deploy keys one-by-one to all the projects kindof sucks. Would be nice to have "team deploy keys", "group deploy keys", or so. Or at least a nice interface for mass-assigning deploy keys to a multitude of projects by administrator - clicking through all the projects kindof sucks now. We are employing a workaround with "dummy" team member added everywhere as a "Reporter", but that is a bit weird for some purposes.
Group deploy keys make sense to me.
We can start from groups page where we can add/remove deploy keys for all projects in group. Something similar to what we did with milestones
