Feature-complete NVMe Namespace Management.
This adds several previously missed but important subcommands to list namespaces and controllers. It also fixes few previously added but just found with real testing to be broken subcommands. Also while there, add possibility to explicitly specify nsid for `nvmecontrol identify` subcommand. It may be useful to specify nsids not having own devices, for example 0xffffffff, or just newly created ones. MFC after: 2 weeks Relnotes: yes Sponsored by: iXsystems, Inc.
