As said, it's loaded as it was a storage plugin shipped by us with the single
addition of having some API compatibility checking to ensure that it's only
load if actually compatible.

Effectively it can have the signature of the base plugin:
https://git.proxmox.com/?p=pve-storage.git;a=blob;f=PVE/Storage/Plugin.pm;h=7f04e85ae8cd00748f3286a6fdaae64992ff22d8;hb=a43a796c6436ec54c47b7c1a758335692125f534

Among that there are list-, create-, delete-, snapshot-, activate- and deactivate-,
map-, unmap- volume methods in the class signature, so full volume control and not
more than we call from user sites.
