Mihnea Saracin b310077093 Fix resize of filesystems in puppet logical_volume
After system reinstalls there is stale data on the disk
and puppet fails when resizing, reporting some wrong filesystem
types. In our case docker-lv was reported as drbd when
it should have been xfs.

This problem was solved in some cases e.g:
when doing a live fs resize we wipe the last 10MB
at the end of partition:
https://opendev.org/starlingx/stx-puppet/src/branch/master/puppet-manifests/src/modules/platform/manifests/filesystem.pp#L146

Our issue happened here:
https://opendev.org/starlingx/stx-puppet/src/branch/master/puppet-manifests/src/modules/platform/manifests/filesystem.pp#L65
Resize can happen at unlock when a bigger size is detected for the
filesystem and the 'logical_volume' will resize it.
To fix this we have to wipe the last 10MB of the partition after the
'lvextend' cmd in the 'logical_volume' module.

Tested the following scenarios:

B&R on SX with default sizes of filesystems and cgts-vg.

B&R on SX with with docker-lv of size 50G, backup-lv also 50G and
cgts-vg with additional physical volumes:

- name: cgts-vg
    physicalVolumes:
    - path: /dev/disk/by-path/pci-0000:00:0d.0-ata-1.0
    size: 50
    type: partition
    - path: /dev/disk/by-path/pci-0000:00:0d.0-ata-1.0
    size: 30
    type: partition
    - path: /dev/disk/by-path/pci-0000:00:0d.0-ata-3.0
    type: disk

B&R on DX system with backup of size 70G and cgts-vg
with additional physical volumes:

physicalVolumes:
- path: /dev/disk/by-path/pci-0000:00:0d.0-ata-1.0
    size: 50
    type: partition
- path: /dev/disk/by-path/pci-0000:00:0d.0-ata-1.0
    size: 30
    type: partition
- path: /dev/disk/by-path/pci-0000:00:0d.0-ata-3.0
    type: disk
