Eric Young 7feb62197d ScaleIO: Prevent usage of unsafe volumes
It is possible for thick volumes, created from storage pools
which have zero-padding disabled, to contain previous data. This
change prevents these volumes from being created by default. A
user can override this behavior by acknowleding the possibility
with a configuration option.

Removed the ability to create thick volumes in a ScaleIO Storage Pool
that has zero-padding disabled; creation of thin volumes from these
pools is allowed. A new configuration option has been added to
override this new behavior and allow thick volumes, but should not
be enabled if multiple tenants will utilize thick volumes from a shared
Storage Pool.
