[PVE-User] Add runcmd and custom parameters in Cloudinit

[José Manuel Giner]

Hello Dietmar,

thanks for answering. If I understand correctly, you propose to make a 
customized installation of the operating system and then install 
cloudinit and convert it to template.

But this approach is much more complicated to manage over the time. If 
we want to provide more specific software, you must create a template 
for each of them.

It does not make much sense to have 10 or 20 templates of Ubuntu 18.04, 
when we can have only 1 and configure it in the first boot with a single 
command that allows you to execute your own script that applies the 
configuration you want. I understand that this is the great advantage of 
Cloudinit.

For example, if I want to provide an installation with cPanel, within 3 
months when cPanel pulls out a new version I would have to prepare a new 
template and repeat the same job every 3 months, however if I could 
execute a script on the first startup it would be valid regardless of 
when it is run as it would always provide an installation of the latest 
version of cPanel available.

In the same way that the SSH key can be added in a very simple way with 
the interface, a key in each line, the parameter runcmd could be added 
with a command in each line. That's why I think it's simple to develop.

Or am I forgetting something?

Thanks!
