Each property will have an entry with the following info:
- edit : boolean - is this property editable after pool creation
- type : str - either bool, bool_alt, size, numeric, or string
- values : str - list of possible values
.. warning::
This data is probed from the output of 'zpool get' with some suplimental
data that is hardcoded. There is no better way to get this informatio aside
from reading the code.
