hidpl-red: Create snapshot, and stop syncing xattrs 

* We now take a ZFS snapshot after every backup.
* rsync excludes temp directories.
* rsync skips syncing extended attributes.  This is because:
** We can't set the selinux xattr all the time, because CentOS6 and CentOS7 have different contexts and file types.
** We can't use custom xattrs, because ZFS doesn't support them on symlinks.
* The path stored in the variable is now relative (although relative to root).  This is needed for the `zfs snapshot` command.
