[PATCH storage v2 0/2] fix #7598: qemu-img: increase timeout for image resize

[Jakob Klocker <j.klocker@proxmox.com>]

Image resizing currently has a timeout of 10 seconds, which can fail
on slow disks and leave the VM in a state where the disk is updated,
but the VM config isn't. 

Since there is no deterministic way to check, with less overhead, if
this is the case, increasing the timeout is the most pragmatic
solution. The resize is only called in a worker context anyway,
therefore this patch series mirrors the ZFS timeout: it increases
the timeout in a worker context to 1 hour; as a fallback for a 
non-worker context the timeout stays 10 seconds.

Additionally there was a minor refactoring: the timeout parameter for
qemu_img_resize was dropped, since the timeout can't be set through
the PVE API and was always hardcoded to 10 seconds.

Changes since v2
-----------------

- drop the timeout parameter in qemu_img_resize
- increase the timeout instead of querying the disk information
(see v1 for more info. Thanks @Fabian)
