More commands will be added to nvmecontrol. Also, there will be a few more vendor commands (some of which may need to remain private to companies writing them). The first step on that journey is to move to using linker sets to dispatch commands. The next step will be using dlopen to bring in the .so's that have the command that might need to remain private for seamless integration. Similar changes to this will be needed for vendor specific log pages. Sponsored by: Netflix Differential Revision: https://reviews.freebsd.org/D18403
