Since systemd v239, Exec* binaries are resolved from PATH when they
are not-absolute. Switch to this by default for ease of downstream
maintenance. Many downstream distributions move individual binaries
to locations that existing compile-time configurations cannot
accommodate.

Extend the change made in ae12b02 to verify the zfs kernel
modules are loaded to the rest of the OpenZFS services. If
the modules aren't loaded the neither the share, volume, or
and zed services can be started.

Historically a dynamic misc minor number was registered for the
/dev/zfs device in order to prevent minor number collisions. This
was fine but it prevented us from being able to use the kernel
module auto-loaded which requires a known reserved value.
Resolve this issue by adding a configure test to find an available
misc minor number which can then be used in MODULE_ALIAS_MISCDEV at
build time. By adding this alias the zfs kmod is added to the list
of known static-nodes and the systemd-tmpfiles-setup-dev service
will create a /dev/zfs character device at boot time.
This in turn allows us to update the 90-zfs.rules file to make it
aware this is a static node. The upshot of this is that whenever
a process (zpool, zfs, zed) opens the /dev/zfs the kmods will be
automatic loaded. This even works for unprivileged users so there
is no longer a need to manually load the modules at boot time.
As an additional bonus the zed now no longer needs to start after
the zfs-import.service since it will trigger the module load.
In the unlikely event the minor number we selected conflicts with
another out of tree unregistered minor number the code falls back
to dynamically allocating it. In this case the modules again
must be manually loaded.
Note that due to the change in the method of registering the minor
number the zimport.sh test case may incorrectly fail when the
static node for the installed packages is created instead of the
dynamic one. This issue will only transiently impact zimport.sh
for this single commit when we transition and are mixing and
matching methods.

Some redundancy is present in the systemd dependencies, as
noticed in PR#6764. Existing setups might rely on these quirks,
so these cleanups have been moved to the development branch.

* Disable zfs-import-scan.service by default. This ensures that
pools will not be automatically imported unless they appear in
the cache file. When this service is explicitly enabled pools
will be imported with the "cachefile=none" property set. This
prevents the creation of, or update to, an existing cache file.
$ systemctl list-unit-files | grep zfs
zfs-import-cache.service enabled
zfs-import-scan.service disabled
zfs-mount.service enabled
zfs-share.service enabled

* Change services to dynamic from static by adding an [Install]
section and adding 'WantedBy' tags in favor of 'Requires' tags.
This allows for easier customization of the boot behavior.
* Start the zfs-import-cache.service after the root pivot so
the cache file is available in the standard location.
* Start the zfs-mount.service after the systemd-remount-fs.service
to ensure the root fs is writeable and the ZFS filesystems can
create their mount points.
* Change the default behavior to only load the ZFS kernel modules
in zfs-import-*.service or when blkid(8) detects a pool. Users
who wish to unconditionally load the kernel modules must uncomment
the list of modules in /lib/modules-load.d/zfs.conf.

For consistency all systemd unit files and init scripts now share
the same names. This prevents an issue where the zed is started
twice on systems where both the systemd and sysv infrastructure is
installed concurrently.
For backward compatibility a 'zed' alias has been added. This
allows the user to interact with the service using either the
name 'zed' or 'zfs-zed'.
