Add provider info to network for update
Ml2 Plugin is not sending provider info
while update_network to mechanism update_precommit,
due to which network becomes un-usable, This patch
extends the updated_network to include provider info.

Title:
Update to existing neutron network results in un-usable network
Status in networking-odl:
Confirmed
Status in neutron:
Fix Released
Bug description:
Updating an existing Neutron Network with the OpenDaylight V2 Driver,
renders that Neutron Network un-usable inside OpenDaylight Controller.
This is because, when we update existing network the ML2 ODL-V2 Driver
removes the network-type and segment-information when the update-
network REST API is invoked towards the ODL controller. This results
in Neutron Northbound in the ODL controller leaving the network with
no provider-type and thus renders that network un-usable further for
any operations.
Steps for the problem:
neutron net-create ghi
neutron net-update ghi --description "bye"
Below is the Ocata V2 ML2 Driver logs when the incident occurred:

Similar trials on Newton release with V2-Driver for ML2 works correctly. The logs from Newton runs thus:
As you can see below, during the update-network REST API invocation to ODL Controller, the ML2 V2 Driver supplies the provider-type attributes to ODL Controller, thereby enabling ODL controller to retain that information in the Neutron Network.
