Support ZFS! Also bugfixes.

This release adds ZFS support as well as some additional bug fixes and minor improvements. Details below:

• ZFS support can be enabled in bastille.conf: bastille_zfs_enable="YES"
  • If ZFS enabled, zpool must be defined in bastille.conf: bastille_zfs_zpool="ZPOOL_NAME"
• ZFS options can be configured in bastille.conf. Default: "-o compress=lz4 -o atime=off"
• resolv.conf options added in previous release (0.3.20190522) replaced with simpler /path/to/resolv.conf.
  • Defaults to host /etc/resolv.conf, but can be any valid resolv.conf.

Bugfixes
