Joseph Benden 1fdecc6680 Add FreeBSD support for ZFS datasets and pools
The following new resources have been added; however, they
presently only support FreeBSD and similar.

* `zfs_dataset`: tests if a named ZFS dataset is present
  and/or has certain properties.
* `zfs_pool`: tests if a named ZFS pool is present and/or
  has certain properties.

Additionally, the `mount` resource has been reworked to
include support for FreeBSD; while the existing class
was renamed to LinuxMountParser.

Unit-tests were added for all of the above.
