[UI] 'Configure Interfaces' page doesn't work if node has OVS network bond

[Artem Panchenko]

Fuel version info (9.0 build #396): http://paste.openstack.org/show/505332/

It's possible to configure OpenVSwitch as provider for network bonds using CLI, but that breaks 'Configure Interfaces' page on Fuel UI:

Uncaught TypeError: Cannot read property 'mode' of undefined

AFAUI it's because 'releases' don't provide availability/properties info about 'ovs' type in 'network_metadata'->'bonding', for example:

http://paste.openstack.org/show/505333/

Steps to reproduce:

1. Create cluster
2. Add 1 node
3. Go to CLI and download interfaces YAML: fuel node --node-id 1 --network --download
4. Edit the yaml file and create new bond with type 'ovs', for example: http://paste.openstack.org/show/505335/
5. Upload updated yaml file to API: fuel node --node-id 1 --network --upload
6. Open 'Configure Interfaces' page for the node

Expected result:

- interfaces/networks configuration works via GUI

Actual:

- UI page doesn't work

The issue occurs because there is no 'ovs' bonding type here: https://github.com/openstack/fuel-web/blob/stable/mitaka/nailgun/nailgun/fixtures/openstack.yaml#L380

Fuel UI's code relays on this bonding type list.
