[PATCH-SERIES docs/storage 0/3] close #7204: document and check that thin pools have zeroing enabled

[Fiona Ebner <f.ebner@proxmox.com>]

There were a bunch of new reports in the last week. Not sure why,
maybe a bogus tutorial out there or something along those lines.

Thin pools with zeroing during allocation turned off are currently not
supported for VM images. Using such a pool may lead to data
corruption for various operations like drive mirror.

Document this and add a check in the storage plugin upon storage
activation.

In the future, a dedicated storage configuration option could be
introduced that can be checked by volume_has_feature() and enforced
upon storage activation.
