Add note pointing to cloud-init images to _posts/2020-11-28-first-11-things-proxmox.md (#161)

The documentation at https://pve.proxmox.com/pve-docs/chapter-qm.html gives a really nice and easy-to-follow guide on how to set up templates with cloud-init support that do all the steps described here on their own. Debian and Ubuntu offer their official images under

https://cloud.debian.org/images/cloud/

and

https://cloud-images.ubuntu.com/.

I don't know if this guide would be the right place for it, but resizing a vm's hard disk is as easy as

```bash
qm resize 123 scsi0 +10G
```

where `123` is the vm's id, and `+10G` the amount the disk should be increased by (both Debian and Ubuntu's default disk size is 2 gb, so not a lot 😅 )

Hope this helps!
