Subject: [PATCH] fix #2315: api: have resize endpoint spawn a worker task

Similar to the corresponding endpoint for containers. Because disks
are involved, this can be a longer running operation, as is also
indicated by the 60 seconds timeout used in qemu_block_resize() which
is called by this endpoint.

This is a breaking API change.
