Public bug reported:

Consider the following scenario, where two nova-compute nodes are
configured to different vcenter with same cluster named "Cluster1":

Compute-Node #1:
-----------------------
hostname:  devstack1
vmware.host_ip:  10.1.0.12
vmware.cluster_names:  Cluster1   << Same cluster name


Compute-Node #2:
-------------------------
hostname:  devstack2
vmware.host_ip:  10.1.0.13
vmware.cluster_names:  Cluster1   << Same cluster name

hypervisor_hostname=domain-c26(Cluster1)


 In this scenario, VC driver creates the same value for  compute_nodes.hypervisor_hostname  as mentioned here.

------------------------------------------------
Compute_node | hypervisor_hostname
------------------------------------------------
#1 | domain-c26(Cluster1)
#2 | domain-c26(Cluster1)
------------------------------------------------

 Because same compute_nodes.hypervisor_hostname is created for more than
one clusters, it creates the following issues in the horizon:

1. In admin->Hypervisors, the same CPU, Memory utilization is reported for both the clusters
2. In admin -> Hypervisors-> [Click on Hypervisor #1]->, the details page reports the same list of instance for both the clusters.

Though the issue is seen in the horizon, the actual root cause is
because vcdriver creates the same hypervisor_hostname for both the
clusters.

so this bug is filed to fix this issue, to create the hypervisor_hostname as follows:
<vmware.host_ip (vmware.cluster_name)> 

Ex: 10.1.0.12 (Cluster1)
