Add zfs create dryrun
Adds the ability to sanity check zfs create arguments and to see the value of any additional properties that will local to the dataset. For example, automation that may need to adjust quota on a parent filesystem before creating a volume may call `zfs create -nP -V <size> <volume>` to obtain the value of refreservation. This adds the following options to zfs create: - -n dry-run (no-op) - -v verbose - -P parseable (implies verbose) Reviewed-by: Ryan Moeller <ryan@ixsystems.com> Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Reviewed-by: Matt Ahrens <matt@delphix.com> Reviewed-by: Jerry Jelinek <jerry.jelinek@joyent.com> Signed-off-by: Mike Gerdts <mike.gerdts@joyent.com> Closes #8974

# DESCRIPTION:

# zfs create -P without -n should be verbose about dataset creation.

# STRATEGY:
|

# 1. Attempt to create a file system and a volume using various properties
|
||||
# and -P
|
||||
# 2. Exercise the combination of -p and -P.
