Add ZFS element

Browse Source 
ZFS filesystem is going to be used for replication feature by
Manila Generic share driver.
So, add appropriate Manila image element as optional and enabled by default.

Set env var 'MANILA_ENABLE_ZFS_SUPPORT' to any value other than 'yes' to
disable its installation.

# NOTE(vponomaryov): this approach of ZFS installation is valid for
# Ubuntu 14.04 (Trusty) and is very likely to be different for other releases.
# Also, ZFS should be installed in 'post-install.d' section because its
# dependency 'dkms' is installed in 'install.d/99-dkms'.
# Presense of 'ARCH' env var blocks DKMS from building new dynamic kernel
# modules. So, unset it temporary.
