lvm_pv: new module for LVM Physical Volumes

[klention]

SUMMARY

This pull request introduces a new lvm_pv module for managing LVM Physical Volumes. The module provides comprehensive functionality for:

• Creating and removing physical volumes
• Resizing existing PVs (with automatic device rescan capability)
• Forceful operations when needed
• Full idempotency and check mode support

Key features:

• Supports all basic PV operations (pvcreate, pvremove, pvresize)
• Automatically handles device rescans before resize operations
• Provides clear status messages and change detection
• Includes thorough parameter validation and error handling

The module fills a gap in Ansible's storage management capabilities, complementing the existing lvg and lvol modules.

Thanks for your contribution! Two first quick suggestions:

• Please take a look at https://github.com/ansible-collections/community.general/blob/main/CONTRIBUTING.md#creating-new-modules-or-plugins in case you didn't.
• How about naming the module lvm_pv?

Hi @klention

Thanks for your contribution. I left some initial comments.

You might want to consider using CmdRunner. See https://docs.ansible.com/ansible/latest/collections/community/general/docsite/guide_cmdrunner.html for more details.

A couple of (minor) suggestions, other than that LGTM

Please don't forget to add tests, otherwise this won't get merged. (See https://github.com/ansible-collections/community.general/blob/main/CONTRIBUTING.md#creating-new-modules-or-plugins.)

Hi @klention Thanks for the updates, it is looking very good now.

I just spotted a couple of minor things, but other than that it is good to go.

Thank you for your guidance and support!
I just applied your suggestions.
Please let me know if anything else is needed.

LGTM! Thanks for your work on the module!

Better adjust the YAML list indentation to the style all other modules and plugins use:
