Poolsman preview 3 released

Today's Preview 3 release is not big, but very helpful in some cases. We are still working on a massive set of features in part of pools expansion and disks replacement, and decided to leave it for the next release. The current Preview 3 version includes:

1. Checking that ZFS is installed. If it's not installed, Poolsman proposes to open the installation manual for your operating system.
2. Checking that ZFS is running. If not, Poolsman proposes to start it and allows to preview the start command.
3. Fix of various issues on RHEL 8 based distros (including Rocky Linux 8) related with an old version of lsblk tool.
4. Fix of various issues related with the case when the system language is not English.

Wishing you a Happy New Year from the Poolsman Team. Thanks to all our users, it's a pleasure to make Poolsman for you.
