Subject: [PATCH 1/6] Use pvs info from static data to get PV size in PVSize
No need for a special code for this, we can reuse the existing
code from LVM static data.

Subject: [PATCH 3/6] Update PV format size after adding/removing the PV
to/from the VG
Unfortunately LVM substracts VG metadata from the reported PV size
so we need to make sure to update the size after the vgextend and
vgreduce operation.

For existing PVs we need to check the format size instead of
simply expecting the format is fully resized to match the size of
the underlying block device.
