Title: Changing zfs rollback options from '-r' to '-Rf'

Details:

```
zfs rollback [-rRf] snapshot
Roll back the given dataset to a previous snapshot. When a dataset is rolled back, all data that has changed since the snapshot is discarded, and the dataset reverts to the state at the time of the snapshot. By default, the command refuses to roll back to a snapshot other than the most recent one. In order to do so, all intermediate snapshots must be destroyed by specifying the -r option.

The -rR options do not recursively destroy the child snapshots of a recursive snapshot. Only the top-level recursive snapshot is destroyed by either of these options. To completely roll back a recursive snapshot, you must rollback the individual child snapshots.

-r Recursively destroy any snapshots more recent than the one specified.
-R Recursively destroy any more recent snapshots, as well as any clones of those snapshots.
-f Used with the -R option to force an unmount of any clone file systems that are to be destroyed.
