HYD-6781 Documentation update about removing datasets from zpools

IML documentation should be updated to explain the following:

Zpools do not appear on the volumes page after the user removes a
filesystem. This is because the zpools still have IML-created datasets
when the filesystem is removed. IML cannot destroy the datasets when the
user removes a filesystem because otherwise the filesystem would not be
recoverable. Users will have to remove the datasets manually (as per ZFS
documentation) before reusing the zpools as volumes in IML.

  - Bump help-docs to 1.2.0.
