vmdk_ops does not report attached volumes correctly: inspect volume and vmdk_ops list volumes results are different and getting error "vm doesn't belong to any tenant"

[shuklanirdesh82]

Environment Details:
#VMs: 2 photon vms (VM1, VM2)
ESX: VMware ESXi 6.0.0 build-3620759
Datastore: vmfs

Steps to Reproduce:

1. docker volume create --driver=vmdk --name=vmwDataVol -o size=10gb (on VM1)

root@photon-EHiCjpUvt [ ~ ]# docker volume create --driver=vmdk --name=vmwDataVol -o size=10gb
vmwDataVol

2. make sure volume is visible to another vm (VM2) and inspecting volume should say 'detached'

root@photon-w3ktCykjv [ ~ ]# docker volume ls
DRIVER              VOLUME NAME
vmdk                vmwDataVol

3. docker run --rm -it -v vmwDataVol:/mnt/myvol2 busybox
4. docker volume inspect vmwDataVol (on VM2)

[
    {
        "Name": "vmwDataVol",
        "Driver": "vmdk",
        "Mountpoint": "/mnt/vmdk/vmwDataVol",
        "Status": {
            "access": "read-write",
            "attach-as": "independent_persistent",
            "attached to VM": "photon2",
            "capacity": {
                "allocated": "155MB",
                "size": "10GB"
            },
            "created": "Wed Nov 16 18:57:57 2016",
            "created by VM": "photon2",
            "datastore": "datastore",
            "diskformat": "thin",
            "fstype": "ext4",
            "status": "**attached**"
        },
        "Labels": {},
        "Scope": "global"
    }
]

5. on ESX: list volumes

[root@promc-2n-dhcp105-97:/vmfs/volumes/4fc608aa-828f03c0-d4a2-d4ae52794a7a] /usr/lib/vmware/vmdkops/bin/vmdkops_admin.py ls
Volume           Datastore  Created By VM  Created                   Attached To VM  Policy  Capacity  Used      Filesystem Type  Access      Attach As               
---------------  ---------  -------------  ------------------------  --------------  ------  --------  --------  ---------------  ----------  ----------------------  
vmwDataVol       datastore  photon2        Wed Nov 16 18:57:57 2016  detached        N/A     10.00GB   175.00MB  ext4             read-write  independent_persistent

Expected Result:
while listing down volume, vmdkops command should say vmwDataVol is attached to VM1

Actual Result:

[root@promc-2n-dhcp105-97:/vmfs/volumes/4fc608aa-828f03c0-d4a2-d4ae52794a7a] /usr/lib/vmware/vmdkops/bin/vmdkops_admin.py ls

---------------  ---------  -------------  ------------------------  --------------  ------  --------  --------  ---------------  ----------  ----------------------

Needs to get the VM name from the attached VM UUID in the KV. I'll fix this. Admin CLI should call vol_info in vmdk_ops.py and get use that data vs. reading KV and interpreting that.

Fixed via #745
