VM launch fails . Subnet uuids different in API server and neutron

[Sachin Bansal]

This is on Icehouse ubuntu build 55, single node 10.204.217.64

Networks / subnets created from Contrail UI. Subnet uuid in api server and
neutron don¹t seem to match.

Neutron:
--------
95f82c7c-cdbb-4c72-94e1-2b7a03b475cf | | 11.1.1.0/30 | {"start":
"11.1.1.2", "end": "11.1.1.2"} |
| f8940525-86dd-4d02-b606-39437c9a0d5d | | 10.1.1.0/30 | {"start":
"10.1.1.2", "end": "10.1.1.2"}

API Server:
-----------
"href":
"http://10.204.217.64:8082/network-ipam/edf3f519-373a-4690-80f6-eb1bbf16f7f
b²,

{"subnet": {"ip_prefix": "11.1.1.0", "ip_prefix_len": 30},
"subnet_uuid": "354fa5e2-165f-46b0-84f1-539280b88b92²,

If the API client updates a network object with subnets and does not send a subnet_uuid, we were allocating a new UUID. If the subnet already exists, we should reuse the subnet_uuid. Now, we read from cassandra before generating a new UUID.
