taskWaiter.waitTask prevents vsphere provider to terminate disk extension

[F.B.]

jujud versions : 2.4.7, 2.5.0
Fault location : provider/vsphere/internal/vsphereclient/client.go, function extendDisk

when called upon root-disk constraint, taskWaiter.waitTask(ctx, task, "extending disk") never gives up and prevents further actions (powering on, ...).

If bypassed by a simple time.Sleep giving enough time for the disk extension, everything's fine, the VM starts and is correctly deployed.

That's the problem described in https://bugs.launchpad.net/juju/+bug/1790183
