Users reported[1] about failing backups to PBS when having a large amount of files in a directory.

proxmox-backup-client has already 'entries-max' implemented. The default value is also a kind of DOS prevention feature. Overriding this parameter needs at least 'Sys.Modify' permissions.

This patch series makes the new optional parameter 'pbs-entries-max' available in vzdump and vzdump.conf.
