[3.0.1.0-23 kilo] can't create a policy in UI with service chain for a tenant with a space in name

[Robert Rosiak]

Steps to reproduce:
1. Create w new tenant with space in name - eg. "CLIENT A".
2. Create for this tenant on contrail UI a new v1 service chain - eg. "VAS55"
3. Try to create a new policy in contrail UI with a service instance "VAS55"

The contrail UI will not add a correct policy, because the apply_service property will be stripped:

curl -H "X-Auth-Token: 715799835fba4549a0fd0fa87dd13d82" http://localhost:8082/network-policy/16e7fb8c-d6b5-4f90-87a4-a6f6a6600049 | python -mjson.tool

...
"network_policy_entries": {
            "policy_rule": [
                {
                    "action_list": {
                        "apply_service": [
                            "default-domain:CLIENT"
                        ],
                        "gateway_name": null,
                        "log": false,
....

The apply_service property value should be: "default-domain:CLIENT A:VAS55"

Here's output for service-instance fq_name values:

curl -H "X-Auth-Token: 715799835fba4549a0fd0fa87dd13d82" http://localhost:8082/service-instance/91453c1f-8494-4e31-86bd-b668e8ca83a8 | python -mjson.tool
{
    "service-instance": {
        "display_name": "VAS55",
        "fq_name": [
            "default-domain",
            "CLIENT A",
            "VAS55"
        ],
        "href": "http://localhost:8082/service-instance/91453c1f-8494-4e31-86bd-b668e8ca83a8",
        "id_perms": {
....
