Import storage pools or list pools available for import
zpool : string
Optional name of storage pool
new_name : string
Optional new name for the storage pool
mntopts : string
Comma-separated list of mount options to use when mounting datasets
within the pool.
force : boolean
Forces import, even if the pool appears to be potentially active.

Searches for devices or files in dir, multiple dirs can be specified as
follows: ``dir="dir1,dir2"``
no_mount : boolean
Import the pool without mounting any file systems.
only_destroyed : boolean
Imports destroyed pools only. This also sets ``force=True``.
recovery : bool|str
false: do not try to recovery broken pools
true: try to recovery the pool by rolling back the latest transactions
test: check if a pool can be recovered, but don't import it
nolog: allow import without log device, recent transactions might be lost
.. note::
If feature flags are not support this forced to the default of 'false'
.. warning::
When recovery is set to 'test' the result will be have imported set to True if the pool
can be imported. The pool might also be imported if the pool was not broken to begin with.
