Leadership Communications Policy: Initial commit
    
    This commit introduces a new Fedora Council policy that deals with how
    and where Fedora leadership groups communicate. At time of commit, this
    policy is still in a draft form and has not yet had the required two-
    week community feedback process required for adding or changing official
    Fedora policies.
