Add verification modules for autoyast_lvm

[JRivrain]

Add 3 modules in autoyast_lvm to validate autoyast profile, and look if the lvm objects are actually present and looking good after install.
Includes also a modification of vaidate_lvm to work in different scenarios.

we have this module for lvm validation https://openqa.suse.de/tests/4428112#step/validate_lvm/9 do you have some run where we can see what is failing and if we can consider to adapt it to use it here?

Will need modifications, as it's designed for a single disk, and here we have two. Probably not so difficult to achieve.

So, I adapted autoyast_lvm to work with more than one Physical Volume, and more than one Volume Group. The modifications can appear a bit overkill, but I think it's what it takes to make that module work for different LVM scenarios. I kept also the other module, verify_lvm_parition, to validate that the partitions created reflect what is in the profile. I did not add test data for the latter, as I think the current thing does the job, but I could change this if requested.

Rewrote it, I had over-complicated the thing to an incredible... extent. I realized I just need to sum-up the free PE and total PE, regardless of the VGs.
