[openstack-dev] [Fuel] Distribution of keys for environments

I'm vote for second option, cause if we will want to implement some unified
hierarchy (like Fuel as CA for keys on controllers for different env's)
then it will fit better than other options. If we implement 3rd option then
we will reinvent the wheel with SSL in future. Bare rsync as storage for
private keys sounds pretty uncomfortable for me.
