"docker volume inspect" does not show the current VM name of the VM that created it

[SandeepPissay]

Steps:

1. Create a docker volume
2. run "docker volume inspect", this shows the "created by VM" correctly as below

root@photon-I1RJXlgPS [ ~ ]# docker volume inspect MyVolume
[
{
"Name": "MyVolume",
"Driver": "vmdk",
"Mountpoint": "/mnt/vmdk/MyVolume",
"Status": {
"access": "read-write",
"attach-as": "independent_persistent",
"attached to VM": "photon-2",
"capacity": {
"allocated": "54MB",
"size": "1GB"
},
"created": "Wed Oct 26 23:26:21 2016",
"created by VM": "photon-1",
"datastore": "datastore1",
"diskformat": "thin",
"fstype": "ext4",
"status": "attached"
},
"Labels": {},
"Scope": "global"
}
]

1. Rename the VM from which the volume was created to something other than "photon-1".
2. "docker volume inspect" shows the old VM name.
   root@photon-I1RJXlgPS [ ~ ]# docker volume inspect MyVolume
   [
   {
   "Name": "MyVolume",
   "Driver": "vmdk",
   "Mountpoint": "/mnt/vmdk/MyVolume",
   "Status": {
   "access": "read-write",
   "attach-as": "independent_persistent",
   "attached to VM": "photon-2",
   "capacity": {
   "allocated": "54MB",
   "size": "1GB"
   },
   "created": "Wed Oct 26 23:26:21 2016",
   "created by VM": "photon-1",
   "datastore": "datastore1",
   "diskformat": "thin",
   "fstype": "ext4",
   "status": "attached"
   },
   "Labels": {},
   "Scope": "global"
   }
   ]

Good, the server plugin must figure the name of the VM from its UUID (persist the UUID in the KV instead of name) and pass that on a Get request.

Fixing this for how the attached to VM is shown. Its possible that the VM that created a volume doesn't exist any longer but the current attached to VM is perhaps more interesting to a user - especially if a volume is unusable for some reason and showing up as attached, then at least its good to show the current name of the VM thats attached the volume. the VM that created the volume may not be as interesting. Possibly a "last attached" VM name would also help. Disk goes corrupt (app is unable to use the disk) at the least we can figure which VM used it last. Not this issue may be.
