Initial provider extension implementation. Specify vlan_id using the CLI with admin rights via "net-create --tenant_id <tenant-id> <net-name> --provider:vlan_id <vlan-id>". Also includes provider:vlan_id in reply messages for admins. The extension is supported in the linuxbridge and openvswitch plugins. Partially implements blueprint provider-networks.
