Fix KV files on clone.

[govint]

From ESX 6.5 onwards, the sidecars for the clone destination get created with a random key vs. the key thats used to create the source sidecars. Which is why the ESX service was unable to open and read/write the file after clone. Effectively clone was broken in 6.5 and later.

Fixed and now able to clone volumes fine.

docker volume ls
DRIVER VOLUME NAME
vsphere:latest test@datastore1

docker volume create -d vsphere clone -o clone-from=test
clone

docker volume inspect clone
