[PVE-User] Request New Features for Web-UI

[Toan Pham]

@Thomas - thank you so much for sharing some of your insights about the
requested features.  I'll look forward for the WakeOnLan feature.  So, if
you have a git url (or something) of your development branch, please let me
know so that I can track it and also to learn more about the code for
myself.


@Mark, you have a good point about remote monitoring with Nagios or zabbix.
   thanks, I'll take the Zabbix route since I already have an active
instance.


@Lutz - I have a very similar backup solution to yours except that i use
syncoid to backup an entire zpool to the remote proxmox server.  On the
other hand backup gets initiated from cron but shutdown is initiated from
the remote proxmox server, that because I wanted the remote proxmox server
to shutdown based on various conditions.  Here are my snipplets:


# part of the backup script to initiate backup

                        syncoid -r -sshkey

                        sleep 260;
                        syncoid -r -sshkey
