Feature: When bonding is configured in active-backup, balance-tlb or balance-alb the priority of the ports can be specified. The value range is signed 32-bit integer. A higher number means a higher priority. Reason: We want to close the gaps between team support and bonding support. The customers must be able to move from team to bonding easily. Result: A new property was added to bond-port in NetworkManager. In order to configure it with nmcli the user must specify `bond-port.prio <value>` when creating or modifying the port connection.
