[PATCH v2 15/16] nvmf-autoconnect: add unit file for nvme-monitor.service

[mwilck at suse.com]

From: Martin Wilck <mwilck at suse.com>

Running both this service and the udev-based nvmf autoconnect service
is discouraged. A "Conflicts" directive against nvmf-connect at .service
wouldn't work, because it would cause the monitor to be stopped as soon
as an event arrives. Therefore, mask the udev rules that would start
the parallel discovery.
