Thought a bit more about that, and I think the only real solution is to but the
VM task logs on shared storage. I can imagine to have a new datacenter.cfg option

---/etc/pve/datacenter.cfg----
vm_log_store: <storageID>
------------------------------------

So the user can store the logs on NFS, GlusterFS, or CephFS ...
(or 'local' storage by default)

But we currently have a single big task list per node. We need to split that into several independent
lists, i.e. we need to use one extra task list for each VM.
This is important to avoid locking problems on the shared storage, and to make it easy to delete
all logs for a specific VM.
