Body

As part of our workflow we have points in time in which we like to lock down a branch for merges.
This is mostly performed during large releases / big conflicts.

Luckily there is a feature on GitHub that allows locking branches, such that no one can merge to a locked branch.

The problem is that there is no way to grant this specific permission. I.e there is no option (or at least not one that I found), that can just control the "lock branch" feature on certain branches. This means that only repository admins can perform this action.

Providing a custom role that can do this action will be very beneficial.
