[PATCH qemu-server 4/4] qga: rename guest-fsfreeze to freeze-fs

[Thomas Lamprecht <t.lamprecht@proxmox.com>]

These settings are already in the (QEMU guest) agent property, and we
do not use the guest- prefix for any of the existing properties
(fstrim or freeze-fs-on-backup), and moving freeze-fs-on-backup to a
generic variant is less confusing if one just drops the "-on-backup"
part, i.e. no point in inventing a new name schema just for the sake
of it.

We already rolled this the guest-fsfreeze name to pve-test, so lets
add an alias, but as we do not provide API stability guarantees for
test packages this is really just for convenience for anybody that
tested this, I'm more than fine with dropping such a (never stable)
released key again on a major release with the respective upgrade
check in our pveXtoY tool.
