scripts/vagrant: Add more NVMe emulation options

Current scripts/vagrant allow us to create only a single file for
emulating NVMe with single namespace.
This patch allow to create multiple emulated drives with multiple namespaces.
This patch also allows to emulate OCSSD disks which are used in OCF tests.
