[5.0 Vcenter] No possibility to add new vcenter clusters via fuel.

[Olesia Tsvigun]

Fuel 9.0
fuel-plugin-contrail 8.0 build#557

Steps to reproduce

    1. Connect to a Fuel with preinstalled Contrail plugin.
    2. Create a new environment with following parameters:
       * Compute: KVM/QEMU + vCenter
       * Networking: Neutron with tunneling segmentation
       * Storage: Ceph
       * Additional services: ceilometer
    3. Run script that prepares vmware part for deployment (creates few Distributed
       Switches and spawns virtual machine on each ESXi node)
    4. Configure Contrail plugin settings:
       * dedicated analytics DB
       * Datastore name
       * Datacenter name
       * Uplink for DVS external
       * Uplink for DVS private
       * DVS external
       * DVS internal
       * DVS private
    5. Add nodes with following roles:
       * Controller
       * сompute + ceph-osd
       * ComputeVMWare
       * 2 contrail-vmware
       * Contrail-config + contrail-control + contrail-db
       * Contrail-analytics + contrail-analytics-db
    6. Configure interfaces on nodes.
    7. Configure network settings.
    8. Configure VMware vCenter Settings:
       Add and assign 1 vCenter clusters to compute-vmware.
    9. Deploy the cluster.
    10. Try to add new vcenter cluster in the 'vSphere cluster' field.

Actual resut
New configuration is not saved.

Unfortunately we don't have possibility to change this field after deploy finished. For workaround I added to spawner.py flag --cluster-list that allow to change 'vSphere cluster' field avoiding Fuel UI.
