Backup command requires rsync installed

[jeremysells]

Hi,

First of all, thanks for creating this container! It made setting up a a Chef server really easy.

I am using the container/image quay.io/3ofcoins/chef-server:12.18.14 and I am getting the following errors. Ill try create a pull request for adding rsync

root@7cf394faf939:/# chef-server-ctl backup
Locating rsync..
[ERROR] rsync must be installed in order to run this command

After running (inside the container)

root@7cf394faf939:/# apt update
...
root@7cf394faf939:/# apt install nano rsync

The command runs

---

It might not be an issue with this, but there was a couple of permission issues in the process
