ScaleIO: Prevent usage of unsafe volumes 
It is possible for 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.

This is a squash of the four commits that led to the final state in
rocky to not allow the creation of any type of non-zero-padded volumes
to be created. This adds a config option that defaults to the safe
behavior. It is backporting a new config option, and a change in default
behavior, but it should be acceptable in this case so that the security
vulnerability can be addressed.

Closes-Bug: #1784871
