Some of our customers have been occasionally hitting zfs import failures in Linux because udevd doesn't create the by-id symbolic links in time for zpool import to use them. The main issue is that the systemd-udev-settle.service that zfs-import-cache.service and other services depend on is racy. There is also an openzfs issue filed (see https://github.com/openzfs/zfs/issues/10891) outlining the problem and potential solutions. With the proper solutions being significant in terms of complexity and the priority of the issue being low for the time being, this patch exposes `zfs_vdev_open_timeout_ms` as a tunable so people that are experiencing this issue often can increase it as a workaround.
