Alexander Motin ba405bc811 Add NVMe Namespace Management support to nvmecontrol(8).
This allows create/delete/attach/detach namespaces on new NVMe controllers.
This is only a first user-level part of the bigger change set.  Kernel part
required to detect and handle the configuration changes without reboot is
completely independent and will be added separately.
