storage: Remove support for NVDIMM namespaces

All additional support for NVDIMM is being deprecated and removed, especially
the support for the namespace reconfiguration. However, namespaces configured
in the block/storage mode can be still used for installation.

The `nvdimm` kickstart command is deprecated and will be removed in future
releases.

Resolves: #INSTALLER-3766
