execute lvresize, if size of an lv changes

[StephanSchultchenFactset]

Use Case

if the size of the block device behind a PV is changed, the blk device size change is notices correctly by the os, but the pv will not notice the size change until something calls pvresize $PATH_TO_BLK_DEVICE.

this prevents lvresize from working.

Describe the Solution You Would Like

if the puppet module notices that the size of a lv needs to be changed, it should call pvresize on all physical volumes that are part of the volumegroup that is hosting the logical volume. with this the the puppet module can change the lv size without the need for human interaction.
