Deprecate support for VMWare storage driver

We deprecated vmwareapi virt driver support of puppet-nova during
2023.2 cycle[1] and then removed it in 2024.2 cycle[2] based on
the driver status.

Because we don't expect any users may use VMWare storage driver without
vmwareapi virt driver, this deprecates support for VMWare storage
driver. We aim to remove it in 2024.1 cycle.
