Re-order the Pruning flow

Browse Source 
1. sub-ints have to be removed before their parent, particularly
   bondethernets, because destroying BondEthernet0 will cascade
   destruction of all of its sub-ints. So:
   - first prune_sub_interfaces()
   - then prune_bondethernets()
   - finally prune_phys()
2. for any interface (loop, bvi, sub, phy, bond), prune_addresses()
   before destroying the interface

Update the README with this new flow.
