This patch reverts the removal of the collection of volume stats
from the vCenter. Of course there is a performance hit when
collecting volume stats against a backend as compared to doing
nothing. The problem with not having any stats collection is that
the scheduler can't schedule properly against this driver, especially
when there are multiple of them deployed and heterogeniously against
other backends. This revert fixes existing deployments against
this backend.
This patch includes a new vmware driver config optiont that allows one
to enable the stats collection, so that a deployment with this driver
can actually work with the scheduler. When a driver doesn't report
any statistics, the scheduler has no way to determine the capacity
utilization of the driver and will always assume it can take a
provisioning request. This is especially problematic in a
heterogeniously deployed environment, where other drivers do report
valid stats.
