libnm/trivial: rename enums NML_DBUS_META_INTERFACE_PRIO_INSTANTIATE_* 
We will need more levels of priority. Change the naming
to make room for that.

  sed 's/NML_DBUS_META_INTERFACE_PRIO_INSTANTIATE_LOW/NML_DBUS_META_INTERFACE_PRIO_INSTANTIATE_10/g' `git grep -l NML_DBUS_META_INTERFACE_PRIO_INSTANTIATE_ ` -i

  ./contrib/scripts/nm-code-format-container.sh
