vmware: check datastore availability during create
The vmdk driver does a lazy creation of the volume's backing vmdk
only at attach time. This is done to save on the huge copy cost
if the vmdk needs to be moved 'closer' to the VM instance at
attach time.
Still during a create volume call the driver needs to verify
availability of a suitable datastore that matches the given
storage profile as well as capacity to accommodate the given
volume size. This check needs to happen at three places - create
volume, create volume from snapshot and create volume from another
source volume.
