Add support for the ZNS zone management send command. An internal nvme_zns_zone_mgmt_send() function is created that matches the parameters of the zone management send function in the ZNS specification. Convenience functions are provided for the following Zone Send Actions: Close Zone, Finish Zone, Open Zone, Reset Zone, and Offline Zone. Zone Send Actions not implemented: Set Zone Descriptor Extension.
