New module zpool (#10146)

Browse source 
* Add zpool module

* Add botmeta

* Use str.format instead of f-strings

* Remove nonlocal usage

* Add check to only pass ashift to zpool add

* Extend ansible_spec and remove unnecessary validation

* Apply suggestions and fix style

* Fix indentation of yaml lists

* Add method to normalize vdevs

Fix role: none in vdevs

* Use CmdRunner instead of run_command

* Fix styling and documentation

* Use str.format instead of f-strings

* Make sure vdevs are only required when state is present

* Add support for loop devices and normalize vdev type

* Add integration tests

* Add missing test dependencies for alpine and redhat

* Skip integration tests on rhel10 until there there packages available

* Use package module for better auto detection of package manager on rhel

* Add copyright header

* Skip tests on rhel and remove redhat install requirements

* Ensure loop devices under /dev exist

* Enable usage of files as pool devices

* Remove disk setup

* Use files as disks

* Apply suggestions

* Fix argument_spec
