    Add defaults for interfaces to all.yml

    The values for 'network_interface' and 'neutron_external_interface' are
    missing from all.yml, meaning it is impossible to override them on a per
    node / per group basis. (globals.yml get's top precedence).

    Make these consistent with the rest of the variables and move the
    defaults into all.yml. Operators can still override / update these in
    globals.yml as before, but those wanting more flexibility now have it
    via host / group variables.
