seems like an API change, doesn't it? Maybe (did not checked) we could
add an "async" boolean param and make the return type a optional string, can
you please check if that would work and stay compatible as long as async is not
passed as true.

Then there are again a few cosmetic, but still important, issues:
* even if it's rather obvious the cost adding something like:
  "resize can easily hang for a longer time depending on underlying storage
  and load" is almost zero (takes <10 seconds of one person) and can only
  help to avoid people going to the b
* place the "fix #2315:" first
  https://pve.proxmox.com/wiki/Developer_Documentation#Commits_and_Commit_Messages
* replace the "qemu:" with "disk:", as we're in the qemu-server repository
  the "qemu" doesn't adds much informational value here (like it would in the,
  e.g., pve-manager one).

thanks!
