[pve-devel] applied-series: [PATCH-SERIES v2 manager/storage/container/qemu-server] improve check_volume_access

["Fabian Grünbichler" <f.gruenbichler@proxmox.com>]

with potential for the following follow-up:
- uploading isos/templates or downloading them currently requires 
  Datastore.AllocateTemplate
- deleting isos/templates currently requires Datastore.Allocate

the latter could get a less restrictive check like we already have for 
backup volumes, to allow users with just 'manage templates/isos' 
permissions to remove the stuff they can create ;)
