tui: generate names for bonds, teams and bridges

This makes it more likely that the user will end up with a master
connection that has connection.interface-name property. This makes it
possible for ifcfg plugin to specify the master in the for of device
name (as opposed to UUID) for compatibility with the legacy network
tooling.

This is equivalent to what nmcli does.
