Use vSphere Datastore backend for Glance with vCenter

It takes a lot of time for copying images from Glance (with Filesystem, Swift or Ceph backends) to vCenter Datastore and vice versa when vCenter is used as a hypervisor. Practically, creating a snapshot of 1GB VM may take 15-30 minutes to upload a snapshot from vCenter to Glance. This is the way how Fuel 5.0 and 5.1 work now.

There is a VMDK backend for Glance [0] which stores all the data inside of vCenter Datastore, so the copying process should be much more faster. So, let reuse it in case of vCenter integration.

Whiteboard

Unfortunately, blueprints which you refer above, according to the review(https://review.openstack.org/#/c/58883/), only partially fulfilled. Iet's provide only support for vCenter/ESX storage for glance. Nova-compute also continues to copy the images over the network to the glance, rather than simply register the image in the glance. I'm afraid we will not get performance gain.

[ES] I would consult with VMware team re this issue.
Also please provide a specification for that
