Bugs about Huawei driver support StandaloneNetworkPlugin

[zhaohua]

In setup_server interface of Huawe driver, it will check the network_info['network_type'].
If the 'network_type' is not 'flat' or 'vlan', the setup_server will fail.
But, when using manila StandaloneNetworkPlugin, the 'network_type' can be 'None'(which also represent 'flat'), which cause an unexpected error.

So, should add 'None' as a legal value of 'network_type' .

And when using manila StandaloneNetworkPlugin without 'standalone_network_plugin_segmentation_id', vlan will not be created.
So, use the number of vlan to sort the port is not effective.(This will also affect other network plugins with 'flat' type)

Should add another way to sort the port(maybe the number of logic ip)

Standalone network plugin has two options:
- standalone_network_plugin_network_type
- standalone_network_plugin_segmentation_id

So, statement in bug description is not fully true. It is None by default, that's all. But it can be 'vlan' and can have 'segmentation id'.

So, if your driver expects 'vlan' always, then it is configuration error.

Sorry for the mistake.
This bugs was proposed by our users.They use Standalone network plugin without "standalone_network_plugin_network_type" and "standalone_network_plugin_segmentation_id", and found huawei driver worked unexpectedly.
So we decided to make this change.
I will modify the bug description more reasonable.
